Electronic security in the modern world is of particular importance, since there are securities, intellectual property and other valuables online. To protect your information, confirm the right to own data or check your electronic signature (ES), the Yandex browser has the CryptoPro EDS Browser Plug-in extension. It simplifies the use of low-level signatures; with the plugin, creating and viewing electronic signatures is simple and safe. The addition is required to be used on the websites of financial institutions, for example, when entering the foreign trade office on the website of the Customs Service.

The CryptoPro plugin is supported in Yandex browser and any other web browser (only modern ones) that support dynamic JavaScript code. Available for most popular platforms:

Linux - LSB 3.1 or later;
Windows 2000 (subject to installation of SP4 and IE0) and higher;
iOS 6 and Mac OSX 10/7 and later;
Solaris – from version 10;
AIX 5-7;
FreeBSD from 7.

Almost every computer meets the listed requirements; there are rarely any problems with system components.

Why is the CryptoPro extension used in the Yandex browser?

The main task comes down to working with signatures. Installing CryptoPro Extension for CAdES Browser helps achieve the following goals:

User identification;
Creating a certificate with public keys;
Formation of a register of electronic signatures;
EDS management with public keys;
Certificate owners can generate and manage keys.

What are signatures set to in CryptoPro EDS Browser Plugin for Yandex browser:

Any electronic documents;
Information entered into submission forms;
Files that the user uploaded to the server from a PC;
Messages in text form.

The CryptoPro plugin is mainly used in secure systems, such as online banking or similar resources that are responsible for processing money or important documents. After installing the signature, there will be no doubt that the owner performed the necessary operations with his own hands. Less often it is required to use the CryptoPro add-on for Yandex browser on client portals or when accessing the Internet from the corporate network.

The CryptoPro center will perform a number of useful actions:

Generating your own identifiers of both closed and open types. Supports encryption function;
Creates a request to issue a new certificate on the local network;
Registers requests electronically in the CA Registration Center.
Filling out digital signatures using public keys according to the X.509 standard, version 3 and RFC 3280. Centralized certification of certificates helps to record the key and its attribute for each user;
Information about revoked certificates is sent to all registered users.

How to install the CryptoPro add-on

Installing the CryptoPro module is relatively simple, but the method is slightly different from the standard algorithm of actions. After installing the extension, you must separately install the program from this developer.

How to install:

If CryptoPro CSP was installed previously, then when installing the extension, the plugin icon will not have a red cross and a message will appear that the extension has been successfully installed and is working.

The listed steps are enough to start using the module, but some users complain that the plugin does not start or they cannot open a page that requires the extension.

Why does the CryptoPro plugin not work in the Yandex browser?

If the Yandex web browser does not react in any way to the digital signature after installing the plugin, some of the functions of banking systems will be inaccessible.

Causes of failures and ways to restore operation:

The CryptoPro CSP program is not installed - the most common cause of failure. You can download the file from the link;
The PC was not restarted. Despite the notification after installation, it is often forgotten that you need to restart the computer;
Install the plugin on a clean browser. Before installing the add-on, you should delete the cache from your web browser. Click Ctrl + Shift + Del, in the “Delete records” line, select “For all time” and be sure to check the box next to “Files saved in the cache”;
Inactive extension. If by chance the plugin was deactivated, it becomes clear why nothing is happening. You can easily check the situation by clicking on “Yandex Browser Settings” and selecting “Add-ons”. The CryptoPro plugin is located in the “From other sources” column;
The resource is not in the list of trusted sites. To add a site to the exceptions, you need to find the installed Crypto-Pro program in the system (preferably through a search) and select “CryptoPro EDS Browser Plug-in Settings”. In the “List of trusted nodes” column, enter the domains and subdomains of the site.

If opening a file from the last point does not work, you should right-click on the program and select “Open with...”, where we select Internet Explorer.

Nowadays, document flow is increasingly moving to monitor screens. Standard paper media are being replaced by virtual documents that do not need to be collected, certified, duplicated or stored in an archive. But the use of electronic document management carries with it one inevitable difficulty: the problem of data protection, certification of documents and maintaining privacy. This is where the question arises about the use of special algorithms that perform two functions:

protect the data contained in the file;
certify the electronic document.

Such algorithms execute special programs that have passed the appropriate certification and are designed to encrypt and decrypt certain information. One of these programs is called Crypto Pro.

What is the crypto pro program for?

The Crypto Pro company was founded in 2000 and since then has occupied one of the leading positions in the market of crypto programs and electronic digital signatures.
