Installation and configuration of electronic signature. Cryptopro does not see the JaCarta key, we solve it in a minute Cryptopro 3.6 does not see the flash drive as a carrier

We are often asked the question: how to install a certificate via CryptoPpo CSP. There are different situations: the director or chief accountant has changed, they have received a new certificate from a certification center, etc. Everything worked before, but now it doesn't. We tell you what you need to do to install a personal digital certificate on your computer.

You can install a personal certificate in two ways:

1. Through the CryptoPro CSP menu “View certificates in container”

2. Through the CryptoPro CSP menu “Install personal certificate”

If your workplace uses the Windows 7 operating system without SP1, then install the certificate according to the recommendations of option No. 2.

Option No. 1. Install through the “View certificates in container” menu

To install a certificate:

1. Select Start -> Control Panel -> CryptoPro CSP -> Tools tab and click the “View certificates in the container” button.

2. In the window that opens, click on the “Browse” button. Select a container and confirm your choice with the OK button.

If the message “There is no public encryption key in the private key container” appears, proceed to installing the digital certificate using option #2.

4. If the version of “CryptoPro CSP” 3.6 R2 (product version 3.6.6497) or higher is installed on your computer, then in the window that opens, click on the “Install” button. After this, agree to the proposal to replace the certificate.

If the “Install” button is missing, in the “Certificate for viewing” window, click the “Properties” button.

5. In the “Certificate” window -> “General” tab, click on the “Install certificate” button.

6. In the “Certificate Import Wizard” window, select “Next”.

7. If you have installed version “CryptoPro CSP” 3.6, then in the next window just leave the switch on the “Automatically select storage based on certificate type” item and click “Next”. The certificate will be automatically installed in the “Personal” storage.

Option 2. Install through the “Install personal certificate” menu

To install, you will need, in fact, the certificate file itself (with the .cer extension). It can be located, for example, on a floppy disk, on a token, or on the computer's hard drive.

To install a certificate:

1. Select Start -> Control Panel -> CryptoPro CSP -> Tools tab and click the “Install personal certificate” button.

2. In the “Personal Certificate Installation Wizard” window, click the “Next” button. In the next window, to select the certificate file, click “Browse”.

3. Specify the path to the certificate and click on the “Open” button, then “Next”.

4. In the next window, you can view the certificate information. Click “Next”.

5. In the next step, enter or specify the private key container that corresponds to the selected certificate. To do this, use the “Browse” button.

If you have installed CryptoPro CSP 3.6 R2 (product version 3.6.6497) or higher, check the “Install certificate into container” checkbox.

8. Select the “Personal” storage and click OK.

9. The storage you have chosen. Now click “Next”, then “Finish”. After this, a message may appear:

In this case, click “Yes”.

10. Wait for a message that the personal certificate has been successfully installed on your computer.

That's it, you can sign documents using the new certificate.

If none of the solutions suggested below fix the problem, the key media may have been damaged and requires recovery (see). It is impossible to recover data from a damaged smart card or registry.

If there is a copy of the key container on another medium, then you must use it for work, having first installed the certificate.

Diskette

If you are using a floppy disk as the key container, you must complete the following steps:

1. Make sure that in the root of the floppy disk there is a folder containing the files: header, masks, masks2, name, primary, primary2. Files must have a .key extension and the folder name format must be xxxxxx.000.

the private key container has been corrupted or deleted

2. Make sure that the “Disk drive X” reader is configured in CryptoPro CSP (for CryptoPro CSP 3.6 - “All removable drives”), where X is the drive letter. To do this:

• Select the “Start” menu > “Control Panel” > “CryptoPro CSP”;

?).

Flash drive

If a flash drive is used as the key media, you must complete the following steps:

1. Make sure that in the root of the media there is a folder containing the files: header, masks, masks2, name, primary, primary2 . Files must have a .key extension and the folder name format must be as follows: xxxxxx.000 .

If any files are missing or their format is incorrect, then the private key container may have been damaged or deleted. You also need to check whether this folder contains six files on other media.

2. Make sure that the “Disk drive X” reader is configured in CryptoPro CSP (for CryptoPro CSP 3.6 - “All removable drives”), where X is the drive letter. To do this:

• Select the “Start” menu > “Control Panel” > “CryptoPro CSP”;
• Go to the “Equipment” tab and click on the “Configure readers” button.

If the reader is missing, you need to add it (see How to configure readers in CryptoPro CSP?).

3.

4. Remove remembered passwords. For this:

• Select the “Start” menu > “Control Panel” > “CryptoPro CSP”;
• Select the “User” item and click the “OK” button.

5. Make a copy of the key container and use it for work (see How to copy a container with a certificate to another medium?).

6. If CryptoPro CSP version 2.0 or 3.0 is installed at your workplace, and Drive A (B) is present in the list of key media, then it must be removed. For this:

• Select the “Start” menu > “Control Panel” > “CryptoPro CSP”;
• Go to the “Equipment” tab and click on the “Configure readers;” button
• Select the reader “Disk Drive A” or “Disk Drive B” and click on the “Delete” button.

After removing this reader, working with the floppy disk will be impossible.

Rutoken

If a Rutoken smart card is used as a key carrier, you must complete the following steps:

1. Make sure that the light on the rutoken is on. If the light does not light, then you should use the following recommendations.

2. Make sure that the “Rutoken” reader is configured in CryptoPro CSP (for CryptoPro CSP 3.6 - “All smart card readers”). To do this:

• Select the “Start” menu > “Control Panel” > “CryptoPro CSP”;
• Go to the “Equipment” tab and click on the “Configure readers” button.

If the reader is missing, you need to add it (see How to configure readers in CryptoPro CSP?).

3. In the “Select a key container” window, select the “Unique names” radio button.

4. Remove remembered passwords. For this:

• Select the “Start” menu > “Control Panel” > “CryptoPro CSP” ;
• Go to the “Service” tab and click on the “Remove remembered passwords” button;
• Select the “User” item and click the “OK” button.

5. Update the support modules required for Rutoken to work. For this:

• Disconnect the smart card from the computer;
• Select the “Start” menu > “Control Panel” > “Add or Remove Programs” (for Windows Vista\Seven “Start” > “Control Panel” > “Programs and Features”);
• Select “Rutoken Support Modules” from the list that opens and click on the “Delete” button.

After removing modules you need to restart your computer .

• Download and install the latest version of support modules. The distribution is available for download on the Aktiv website.

After installing the modules, you must restart your computer.

6. You should increase the number of Rutoken containers displayed in CryptoPro CSP using the following instructions .

7. Update the Rutoken driver (see How to update the Rutoken driver?).

8. You should make sure that Rutoken contains key containers. To do this, you need to check the amount of free memory on the media by following these steps:

• Open “Start” (“Settings”) > “Control Panel” > “Rutoken Control Panel” (if this item is missing, you should update the Rutoken driver).
• In the “Rutoken Control Panel” window that opens, in the “Readers” item, select “Activ Co. ruToken 0 (1,2)" and click on the "Information" button.

If the rutoken is not visible in the “Readers” item or when you click on the “Information” button, the message “ruToken memory status has not changed” appears, then the media has been damaged, you need to contact the service center for an unscheduled key replacement.

• Check what value is indicated in the line “Free memory (bytes)”.

Service centers issue root tokens with a memory capacity of about 30,000 bytes as key media. One container takes up about 4 KB. The amount of free memory of a rootken containing one container is about 26,000 bytes, two containers - 22,000 bytes, etc.

If the free memory of a root token is more than 29-30,000 bytes, then there are no key containers on it. Therefore, the certificate is contained on a different medium.

Registry

If the Registry reader is used as a key medium, you must perform the following steps:

1. Make sure that the “Register” reader is configured in CryptoPro CSP. For this:

• Select the “Start” menu > “Control Panel” > “CryptoPro CSP”;
• Go to the “Equipment” tab and click on the “Configure readers” button.

If the reader is missing, you need to add it (see How to configure readers in CryptoPro CSP?).

2. In the “Select a key container” window, select the “Unique names” radio button.

3. Remove remembered passwords. For this:

• Select the “Start” menu > “Control Panel” > “CryptoPro CSP”;
• Go to tab « Service" and click on the "Delete remembered passwords" button;
• Select the “User” item and click the “OK” button.

What to do when an error occurs when sending reports in the SBIS++ Electronic Reporting program "A valid client certificate is missing" or "Access denied"? In this case, the report cannot be sent. The first thing that comes to mind is something with a certificate! However, there is no need to panic: you can fix this error yourself by checking the certificate and configuring the readers correctly. To do this, follow our instructions!

Error in SbiS++: The taxpayer "Name" LLC does not have a valid EDS (electronic digital signature) certificate.

Causes:

• Incorrect update of the SBS++ Electronic Reporting system;
• The carrier of the secret key is missing;
• One of the certificates in the certification chain is not dated;
• There is no valid EDS (electronic signature) certificate;
• The media is missing from the added CryptoPro readers.

Solution:

Checking the presence of digital signature on the media, reloading the certificate in SBS++, performing a system check.

Step 1: Checking the availability of digital signature media

First you need to check the presence of a certificate on the media. If the certificate is installed on removable media, check the presence of the media on your computer.

When you are convinced that the media is present on the computer or the certificate is installed in the computer's Registry, you can begin checking CryptoPro.

Step 2: Launch CryptoPro for verification

To check, you need to launch the CryptoPro program from the Control Panel.

If you have Windows XP, then there are two ways:

1. Start\Settings\Control Panel\CryptoPro CSP.

If you have Windows Vista or Windows 7, then you need to look for the program here:

1. Start\Control Panel\CryptoPro CSP;
2. Start\Control Panel\System and Security\CryptoPro CSP.

The CryptoPro program shortcut is shown in Figure 2. Launch the verification program by double-clicking the left mouse button.

Step 3: Launch Administrator Rights

After the CryptoPro program window appears, you need to run it with administrator rights (this does not always happen automatically). To do this, click on the highlighted link in the lower half of the program window “Run with administrator rights.”

After launch, this inscription will disappear - this means that you launched the program with administrator rights. Now you can start checking the digital signature on the media.

Step 4: View the certificate in the container

To view the certificate, go to the service tab.

A window will open asking you to enter a name for the container. To select a certificate, click the Browse button.

A window will appear on your screen asking you to select a container. Select the container and click OK and Next.

Certificate information will appear in the “Certificates in the private key container” window.

If the viewport displays data necessary certificate, you can continue correcting the error. If not, you see the certificate data of another organization on the screen - browse the certificate, selecting other containers until you find necessary certificate. When the certificate is found, click “Finish” and close the CryptoPro window.

Step 5: Configuring Readers

If the required certificate was still not found in the container selection list, you can view the presence of your media in the added CryptoPro readers. To do this, you need to go to the “Equipment” tab in CryptoPro, click on the “Configure readers” button in the “Private key readers” section.

The “Manage Readers” window will open, click the “Add” button to check the media in the added readers.

The “Reader Installation Wizard” will start, in the first window click “Next”, a window will appear asking you to select a reader.

In the right half of the window, in the “Available Readers” section, see if your media is present in this list. If present, select it and click Next and then Finish. If the required reader is not in the list, it means that the media is already in the list of added ones. You can continue checking.

To reload the certificate, open the “SbiS++ Electronic Reporting” program in the main window, where the “Taxpayer Calendar” is located. Select the desired taxpayer in the “Taxpayer” section and click on the “Edit” panel (for an example, see Fig. 12).

Double-click on an employee and delete his valid certificate using the “Delete” key on the keyboard (for an example, see Fig. 14).

After deleting, double-click on the white field in the “Issued to” column. The “Certificate Creation Wizard” will appear, select “Install from media” and click “Next” (see Figure 15 for an example).

In the next window, select “Upload certificate”, a window will appear with the choice of container (for example, see Fig. 16).

If you click on a certificate with one click, all information about the certificate owner will appear. After selecting the certificate, click “Select” and “Finish”.

After completing the previously performed actions, it is advisable to conduct a full system check by clicking the “Service” button on the top panel and selecting the “System check protocol” item. During a communication session with an operator, windows may appear asking you to install a certificate; respond to all such offers. "Yes". If the system check protocol ends positively, then the system is ready for reporting. In this case, re-sign the report that you tried to send before the error occurred and send it again.

As paper document flow is replaced by electronic one, such a tool as an electronic signature is becoming increasingly important and increasingly widespread. Already, many departments exchange documents exclusively in electronic form, with each legally significant document signed with an electronic signature. It is used when working on electronic trading platforms, when interacting with government information systems (such as GIS GMP, GIS Housing and Communal Services and others) and can even be used for authorization on government portals (such as gosuslugi.ru). There is no doubt that the scope of application of electronic signatures will continue to expand in the future, and therefore it is extremely important for specialists in the field of information technology to understand the principle of operation of an electronic signature and be able to take the necessary steps to install and configure software for working with an electronic signature.

Of course, studying this issue would be worth starting with the federal law “On Electronic Signatures” ( http://www.consultant.ru/document/cons_doc_LAW_112701/ ), which provides definitions of concepts, the legal status of an electronic signature, the procedure for its use and other useful information. However, the purpose of this article is to show how quickly, without going into details, to install an electronic signature, which in some cases, in cases where there is no time for proper study, will be very useful.
We will perform the installation on a computer running the Windows 7 Professional operating system, a private key for an electronic signature on eToken media, and we will use CryptoPro CSP as a crypto provider.
Let's start by installing the necessary software:
- CryptoPro CSP version 3.6 or higher;
- Media driver (when using eToken or Rutoken).
The driver for eToken can be downloaded for free from the following link http://www.aladdin-rd.ru/support/downloads/etoken/ , the driver for Rutoken is available for download here http://www.rutoken.ru/support/download/drivers-for-windows/ .
Other devices, such as a flash drive, smart card or registry, can also be used as a carrier of key information, but it is not recommended to use them as they do not provide a sufficient level of protection of key information from unauthorized access.

Installing an electronic signature key certificate.

After the eToken driver (Rutoken) and the crypto provider CryptoPro CSP are installed, we can begin installing the electronic signature verification key certificate.
Launch the CryptoPro CSP program, go to the “Service” tab and click the “View certificates in the container” button.

In the window that opens, click “Browse”, select the desired owner and click “OK”.

In the next window, do not change anything, click “Next”.


A window will open in which we can see brief information about the user’s certificate (information about the owner, the validity period of the certificate and its serial number).


To view detailed information, click “Properties”. If the root certificate of the certification authority has not yet been installed (as in our case), then in the general tab we will see a message as in the figure below. The current root certificate of a certification authority is usually available for download on the website of the certification authority (the organization that issued the electronic signature).

Return to the previous window and click “Install” to continue installing the user certificate. A message appears indicating that the certificate is being installed. Confirm the installation by clicking the “Yes” button.


A message from eToken PKI will also appear, asking you to write the certificate to eToken. We refuse, click “Cansel”.


The certificate is installed in the certificate store. Click “Finish” to complete the installation.

Installing the root certificate of the certification authority.

Open the file of the root certificate of the certification authority (with the .cer extension) by double-clicking the mouse and clicking the “Install certificate” button.

The Certificate Import Wizard will open. Click “Next”. Then check the “Place the certificate in the following storage” checkbox.


Through “Browse” we specify the “Trusted Root Certification Authorities” folder.

Click “Ok” and complete the installation. A message appears indicating that the operation was successful.

Now, when we open the properties of the user certificate, we will not see the same error.

All we have to do is test the private key container.

Testing.

Open CryptoPro CSP, and in the “Service” tab, click “Test”.

We find the key container through “Browse” or using the corresponding certificate and click “Next”. You will be prompted to enter a pin code for the container. Enter the password and click “Ok”. If you check the “Remember pin code” checkbox, the system will not request it whenever you access the key container (including when signing a document), which is not recommended in order to protect against unauthorized access.
Next, a window will open with information about the presence or absence of errors.

Installing an electronic signature in the register.

It is possible that the private key of an electronic signature needs to be duplicated in order to be used on several computers. In such cases, the optimal solution would be to install the private key of the electronic signature in the registry. For a container created in the registry, you can set a password and thereby limit access to the private key of the electronic signature, which is stored in the container. Removable media, after installation, can be transferred to another user. I note that such a measure is justified in cases where, for example, several employees of one organization (department) use the same signature (for example, the signature of an authority). In other cases, resorting to such measures is not recommended.

Installation of the “Register” reader.

The first thing you need to do is install the reader. This is quite easy to do using the reader installation wizard (adding and removing readers is performed under an account with administrator rights). If, when installing CryptoPro CSP, you checked the “Register reader “Registry”” checkbox, as in the figure below, and it is present in the list of readers, you can immediately proceed to copying the private key container to the registry.


Launch CryptoPro CSP, in the “Equipment” tab, click the “Configure readers” button.

In the window that opens, click “Add”.

The reader installation wizard will start, click “Next”.


From the list in the window on the right, select “Registry” and click “Next”.


Then we set the name of the reader, or leave it unchanged as in our example and click “Next”.


We complete the wizard and click “Finish”.

Copying the private key container to the registry.

The reader is prepared, now you need to copy the container with key information from the eToken removable media to the registry. To do this, go to the main menu of CryptoPro CSP and in the “Service” tab, click the “Copy” button. Through “Browse” we indicate the container that we want to copy to the registry.


The system will then request a password to access the container on removable media (eToken). Enter the password, and in the next window set the name for the key container that will be created in the registry.


In the next window, the program will prompt you to select the media on which you want to burn the container. Select “Registry” and click “Ok”.


Now we need to set a password for the container that we placed in the registry.

Enter the password, confirm and click “OK”.
Now, having launched the function of testing the private key container, in addition to the container on removable media, we will see the created container on the “Registry” reader.
We complete the container testing procedure. If no errors are found, proceed to installing the electronic signature key certificate (if it has not been done previously). The procedure for installing a certificate from the registry is similar to the installation procedure from removable media, and if the owner’s certificate has already been installed from removable media, then installing it again after copying the container to the registry is not required.

4. How to set up email.

Configuring security settings for Outlook Express is carried out according to the following scheme:

1. Select the menu item Tools -> Accounts and open the Mail tab.

2. In the displayed list of accounts, select the one you want to configure and click the Properties button.

3. In the displayed dialog, select the Security tab, which allows the user to specify his personal certificates, which will be used when selecting the user’s personal keys for generating an electronic digital signature and decrypting incoming messages. The certificate selection dialog only displays certificates that have a matching email address and are allowed for email security

5. In the displayed dialog, select the Security tab:

6. In the displayed dialog, set the following modes:

a. Always encrypt messages when sending encrypted mail . Setting the enable mode allows the sender to decrypt the messages he has sent.

b. Include my digital ID when sending singed messages. Setting this mode to automatically add the sender's certificate to all messages. This mode allows you to exchange certificates using a signed message, and then use the resulting certificates to subsequently encrypt messages between recipients.

c. Send messages with an opaque signature / Encode message before signing. When Message Mode is enabled, all attachments will be combined into a single attachment with a digital signature included. If the mode is disabled, the signature is generated as one separate attachment for all attachments.

d. Automatically add sender certificates to my address book. When enabled, certificates sent as part of a signed message will be automatically added to the address book.

e. Check for revoked Digital Ds:

i. only when online. Installing a verification token means that each operation of generating or verifying an electronic digital signature will be accompanied by a certificate revocation check. To check for revocation, a Certificate Revocation List (CRL) is used, information about the location of which is recorded as an addendum in each user’s certificate. By default, this option is not enabled, and Outlook Express does not track whether user keys have been compromised.

ii. Never/Never.

No revocation check is performed.

5. How to sign a document.

There are 2 types of sending a signed document.

The first way is to sign the document itself and the second is to sign the entire letter.

To create and send a signed message:

1. Click the Create Mail button or select the menu item File -> New -> Mail message.

3. To send a signed message, check the status of the Sign button. It should be pressed and the signed message sign should be visible on the right side of the screen.

4. Once the message is ready to be sent, click on the Send button:

The second method is when the file itself is signed. Microsoft Office allows you to attach digital signatures to a specific document. To do this you need:

1. From the Tools menu, select Options, and then open the Security tab.

2. Click the Digital Signatures button.

3. Click the Add button.

4. Select the certificate you want, and then click OK.

For other data formats, you must use the CryptoArm program.

6. CryptoPro expires.

During installation, the product serial number was not entered according to the license you purchased.

7. Mail does not see the certificate.

When setting up email, at the stage of signing the document, the email does not find the required certificate. This happens when the email address that is specified when producing the digital signature does not match the current email address.

8. When installing CryptoPro at the last step, the system displays a message about the incorrect installation of the program and rolls back. What should I do?

The problem occurs due to incomplete (or incorrect) removal of the previous version of Crypto Pro from the computer. To remove files remaining from the previous version, you must use the CryptoPro clear.bat trace cleaning program. You can download the program from here: ftp://ftp.cryptopro.ru/pub/CSP_3_6/clearing.zip

9. Where can I find the public digital signature signature key?

In all signatures issued by our company, the public key is located inside a container on a secure medium. In order to remove it from the container you need to:

When the media is included in the system unit Through the CryptoPro program Start à Control Panel à CryptoPro à Service à View the certificates in the container. In the dialog box that appears, select the required container through the overview à Next. In the window for viewing digital signature public key data, select properties à “Composition” tab à Copy to file and specify the path to save the certificate.

10. CryptoPro does not see the container on the flash drive. Prompts you to select another media.

Depending on what type of media you use, the solutions are different. If you use smart cards such as Rutoken, MSKey, Etoken, then most likely you do not have the drivers installed to work correctly with the key.

If your key is on a USB 2.0 flash drive, then you need to look at the version of the CryptoPro kernel. If you are using CryptoPro 3.0, then you have lost your way. In order to configure it you need to:

When the media is included in the system unit Through the CryptoPro program Start à Control Panel à CryptoPro à Equipment Configure readers Add. In the Reader Installation Wizard window that appears, select Floppy Drive on the right side of the screen (since in CryptoPro all USB drives are defined as floppy disks). In the next window, select the correct name of the flash drive, that is, the name under which the flash drive is identified in “My Computer”.

If you are using CryptoPro 3.6 and the container is not visible, then the media is damaged. It should be provided to the office to determine the status of the key.

11. We have received an electronic signature, what to do next? How to register on the trading platform?

The entire procedure for accreditation, filing an application for participation in the auction and conducting the auction itself is described in the operating regulations of a specific electronic trading platform, which can be found on the website of this platform.
