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, document certification 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, which 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. Developers not only implement individual software products, but also offer ready-made utilities that process documents online through special browser extensions. Crypto-Pro EDS Browser plugin can be purchased on the company’s website, and its installation is possible on all types of popular browsers.

Features of installing browser plugin Crypto Pro

For different browsers The developers have come up with special add-ons that make the plugin easier to operate. For example, for later versions of FireFox there is an add-on that is proposed to be installed immediately after the main part of the process.

Sometimes an error occurs before work and the plugin is unable to create objects.

This problem can be solved quite simply: you should allow add-ons to run separately for specific sites or for all pages visited by the user.

If the plugin is allowed to be used on individual sites, you should go to the desired page and find a separate icon in the search bar indicating the possibility of using the extension:

If the plugin will work with all sites, it should be launched from the “Add-ons” option:

In the list of all possible add-ons, look for CryptoPro CAdES NPAPI Browser Plug-in and allow its use in automatic mode:

For Opera and Yandex browsers, the process of applying the extension will be identical. In the menu we find the “Extensions” option, through which we do not load the necessary plugin.
