How to copy digital signature to another medium. What is an electronic signature - in simple language for beginners in the world of the digital economy. Electronic signature capabilities

If the electronic signature was issued to the PC registry, then you can copy it to a medium using the following instructions.

Step 1. Open CryptoPro and go to the “Service” tab, then click on the “Copy” button as shown in the instructions.

Step 2. In the window that appears, click the “Browse” button to select the electronic signature container you need to copy.

Step 3. In the list of existing containers that appears, select the container you need, which you need to copy to the media and click the “OK” button.

Step 4. Confirm the action by clicking the “Next” button in the window that appears

Step 5. In the window that appears, specify the name of the new container that will be created on the media. The name in the field is entered automatically, so you can simply leave it unchanged. Click the "Done" button.

Step 6. A media selection window will appear. Select the desired medium from the list to which you want to copy the electronic signature. In order to understand which media to select from the list, look at the “Inserted media” field: it will either say “Media is missing,” which means you have selected a non-existent media, or the media name will appear similar to the name in the screenshot. Select and click OK.

Step 7. After you select the media, a window will appear to enter the PIN code for the new electronic signature container. We recommend entering the standard PIN code “12345678”, because... clients often forget or lose their PIN codes, after which the electronic signature has to be reissued. You can set your (different) PIN if you are sure that you will not lose it. After entering the PIN code, click the "OK" button.

Ready. Now the electronic signature container has been copied to the selected medium and you can use it.

If you don’t want to understand these details, we will help. You can even call our engineer to your office.

As a rule, an electronic digital signature is recorded on a USB drive. However, if you need to install a digital signature from a flash drive to a computer, that is, copy the digital signature to a computer, find out in this article how to do it quickly and easily.

Copy digital signature to computer

Of course, carrying a flash drive with you all the time is not always convenient. It may either become unusable, or it may simply not be available at the right time. In this case, a method will come to the rescue in which we copy the digital signature certificate to the computer itself, which will subsequently allow us to do without a USB drive.

In order to copy digital signature to computer, please follow the following instructions:

Insert the USB drive with digital signature into the computer and run the program CryptoPro CSP, go to the tab Service and press Copy….

In the window that opens, select the key container by clicking the button Review.

In the list of user key containers that opens, select a container and click OK.

After selecting a container, its name will appear in the line Key container name. In the next window just click Further.

In the next step, you need to specify information about the new container, for which enter Certificate name (think of any name for the key certificate). After that, click the button Ready.

For again container being created It is possible to set a new password. If you want to set a password, enter it twice in the appropriate fields. If you do not plan to use a password, leave the fields blank and click OK.

So, we have selected the object to copy and indicated the location where the certificate will be stored. Now you need to install this certificate.

In the tab Service click View certificates in container...

Clicking the button Review, in the window that opens, if you noticed, another key container has appeared. Select the newly created container and click OK.

After selecting a new container, click Further.

The window that opens will indicate the certificate to view. Click Install.

As a result, after your actions, a message about the successful installation of the certificate will appear. Click OK.

Ready. The digital signature is installed on the computer.

Can be used if we're talking about about enhanced unskilled signatures.

Kinds EDS, which have the maximum degree of protection, are recorded exclusively on specialized USB devices. Their issuance is provided at all existing certificate points.

Let's look at the flash drive options that people most often try to use for storage means of cryptographic information protection:

Unprotected flash drive. Not suitable for storage confidential information due to open access third parties to it.
Flash drive with built-in encryption function. The device limits, but does not completely prevent, unauthorized access to keys. The danger arises at the moment of transfer EDS to the computer when signing the document.
(token) with a built-in crypto processor. More suitable option for storage EDS. Contains two levels of information protection that are activated at the time of recording EDS and contacting her during the signing process. Signature, recorded on such a storage medium cannot be illegally changed, but the possibility of its theft at the time of transfer to computer software remains.
USB device with built-in shaping function EDS. This type flash drives is a kind of minicomputer - the document to be signed is submitted to the “input” of the device and signed inside it. Such a token is maximally protected from unauthorized access, because signature is not extracted from it. Loading signatures on external devices is not required for its use.

How to write digital signature to a flash drive from another storage medium? Take advantage of opportunities special program CryptoPRO CSP.

Let's give brief instructions to rewrite the certificate:

A clean one is inserted into the computer flash drive for digital signature and carrier signatures.
The CryptoPRO CSP program is being launched.
In the program menu that opens, select the “Service” tab, then press the “ Copy».
Specifies the path to the certificate EDS in the “Overview” menu tab, the selection is confirmed by pressing the “OK” button.
If the system asks for a password, you must enter it. The default number sequence is 12345678.
Assigns a name to the new copy signatures and by clicking the “Finish” button, preparation for copying is completed.
In the dialog box that opens, select a new flash drive and after clicking the “OK” button, enter the password for the copy EDS. You can leave the same password to avoid confusion with access codes or choose a new combination of characters.

How to transfer digital signature from flash drive to flash drive? Simply copy the certificate folder and paste it onto the new media. Take precautions when carrying EDS to a new device!

Using a flash drive as an electronic key

A key is the most accessible method of protecting a computer from access by unauthorized persons. A USB device is a modern analogue of a dongle. How to make an electronic key from a flash drive?

One way is to use a RAM module, whose task is to test each device inserted into the computer. flash drives for compliance with the information stored in the system and, depending on the result of the check, open the login to the system or block it.

Electronic key flash drive works as follows: with each successful login to the system, the information stored in its backup part is overwritten.

The next time you try to log in, the system will compare the credentials flash drives- her serial number, brand, manufacturer and data from the backup part of the USB device.

The module is configured as follows:

The libpam_usb.so library and the utilities necessary to manage the module are installed.
A flash drive is inserted into the USB port - the future key. Using a special command, the module collects all information about flash drive and recording service information on it for subsequent identification of the user.
Enter a command attaching a name flash drives to a specific account.
A check is started to check the correctness of the data entered into the system.
The pam_usb module is given the right to control the system until the key is used. If no suitable flash drives, the system may prompt you to enter your login and password or, according to established settings, block the entrance to it.

Usage flash drives as a key, it does not provide for placing logins and passwords on it, or means of cryptoprotection of information.

Select digital signature

In addition to convenience, such a key storage provides the user with the following benefits:

No need to remember a large amount of information.
Possibility of use flash drives as a means storage information.
Ensuring quick login.
Console auto-protection. When removed from the USB port flash drives work on the computer is automatically blocked.

Document flow in electronic form is introduced into various areas of activity. The core of this system is EDS. It is considered a complete replacement for hand-written signatures, confirms the author document and allows you to make sure that the file has not been modified after signing.

Owners who are using this attribute for the first time are interested in the question “ how to use digital signature"? For the digital signature to work, it is necessary to install a specialized tool for protecting information in cryptographic mode (CIPF) on your personal computer. It is a module responsible for secure data encryption. Only if it is available can anyone sign document, and also protect against unauthorized hacking by unauthorized persons.

If you wish that software started to work, you need to purchase a license issued by a certification center. If it is not available, you can install any third-party crypto provider that complies with GOST. The most common are CryptoPro and VipNet.

If you are afraid that you will not be able to handle the setup on your own, you can contact the CA manager for help. For those who don't know, how to use digital signature from a flash drive, and in general, this is the first time I encountered such signature, it is important to know that the electronic signature issued by one CIPF will not apply to others. If you plan to use several different systems on one PC at once, you should tell the issuance and installation specialist about this. electronic signature.

To sign any document the owner is required to have EDS key, which is known only to him. It is recommended that you read and clarify in advance how to use an electronic key and how to properly store it. It is best to record it on a special medium. If an ordinary flash drive falls into the hands of an attacker, he can easily put his signature on it instead of you. document. Electronic key can contain:

On a specialized token carrier that has good protection and only works when the correct PIN code is entered.
In the cloud located on the server of the certification authority. This allows you to sign digital documentation at any time and in any place convenient for you where there is Internet access.

If you already know how to use a digital signature and yours EDS ready to begin performing her functional duties, register her with the CA and attach a special certificate.

All elements related to electronic signature, including the certificate, are issued by the CA. Each one is stored on a special storage token, which ensures their protection. When any cryptographic operation is performed, a crypto provider to gain access to the key EDS closed type, addresses electronic media. On the website of the certification center you can view the information you are interested in and find out in detail how to use an electronic signature.

Select signature

There are 2 types of documents:

Electronic documentation in a specialized format that allows you to embed an electronic digital signature inside the document.
Informal documentation that does not have a tool for embedding digital signatures.

Once you understand how to use digital signature, you should figure out whether it is possible to embed it inside the file itself. In some cases, special settings are required, but most often a simple version of this program is enough. Using Microsoft Word Most factors depend on the version of the product itself. In programs before 2007 EDS V document is created without auxiliary add-ons, but in versions created a little later, a special CryptoPro Office Signature plugin is required. Speaking of signing files in PDF format, it is worth noting the importance of using Adobe programs Acrobat. With her help in document can be embedded EDS.

Electronic signature Many people use it to work on ETP. To do this, you should complete accreditation, attaching photocopies of the necessary documents signed by the electronic signature, and figure out how to use an electronic signature key. When participating in auctions of this type, all actions must be confirmed electronic signature, since all information is stored on ETP servers.

The person who received document electronic format, can verify the authenticity of the file with digital signature. This can only be done if there is an open key sender. As a result of the test, a special software module allows you to determine whether the signature document and public electronic key.

The relevance of this application signatures is increasing every year. Only some details regarding the scope of its application change, and all other elements remain the same. All you need to do is study in detail, how to use an electronic digital signature.
