Plugin cryptopro ecp browser. To work with an electronic signature in the Internet Explorer browser, you will need the CryptoPro CADESCOM plugin

Cryptographic operations, such as creating an electronic signature or decrypting a file, require access to the user's keys and personal data (for example, to a store of personal certificates). When performing such operations by web applications (using the CryptoPro EDS Browser plug-in), the plugin asks the user for permission to access his keys or personal data.

The user's permission will be requested when activating the CryptoPro EDS Browser plug-in objects.

Trusted Web sites (for example, those on your organization's intranet) can be added to the Trusted Web Sites list. Websites on the trusted sites list will not ask for user confirmation when opening the certificate store and performing operations on the user's private key.

CryptoPro is a plug-in designed to check and create electronic signatures on various documents converted into electronic format and posted on any sites, or in PDF format. Most of all, this extension is suitable for those who often work with banks and other legal organizations that have their own representation in the network.

At the moment, this plugin can be found in the extension/add-on directories for the following browsers: Google Chrome , Opera , Yandex.Browser , Mozila Firefox .

It is also worth remembering that the plugin is distributed absolutely free of charge. Allows you to put or verify signatures on the following types of files/documents:

  • Various forms used for feedback on sites;
  • Electronic documents in PDF, DOCX and other similar formats;
  • Data in text messages;
  • Files that have been uploaded by another user to the server.

Method 1: Installation in Yandex.Browser, Google Chrome and Opera

First you need to learn how to install this extension in the browser. In each program, it is set differently. The plugin installation process looks almost the same for Google and Yandex browsers.

The step by step process is as follows:


You will also have to use this instruction if you are working with Opera, since you will not be able to find this extension in their official application catalog that will work correctly.

Method 2: Installation for Firefox

In this case, you will not be able to use the browser extension for Chrome, since it will not be able to install in the Firefox browser, so you will have to download the extension from the developer's official website and install it from your computer.

Follow these steps to download the extension installer to your computer:


The process of installing the plugin on your computer is simple and takes a little time. You just need to find the executable EXE file that you previously downloaded from the site and install according to its instructions. After it, the plugin will automatically appear in the list of Firefox extensions.

The situation when an error notification occurs when trying to enter your personal account using an ES means that the plugin is not installed or not enabled.

If the plugin is installed, then a notification will appear at the bottom of an attempt to start the add-in. Click the "Allow" button, refresh the page and re-login using the ES. The action may need to be performed multiple times (per disabled plugin add-on).

If the browser did not request permission for the add-on to work(for example, pop-up windows are blocked in the settings), then enable it manually. For this:

1. Click the settings icon in the upper right corner and select "Configure add-ons".


2. In the window that opens, set the condition "Show all add-ons" (1)

Right-click on the name of the add-on under "Crypto-Pro" and select "Enable".

If there are several add-ons in the section, enable each one in turn.


If the plugin has not been installed(i.e. there is no Crypto-Pro section in the add-ons), download and install the plugin with your browser windows closed. An offer to download the plugin will appear along with a browser error notification. Start the installation by clicking the "Run" button (or save the file first, then run it to install the plugin).


After the installation is complete, launch the browser and log in to the site.
