NSD cryptographic service is a Windows-based application used for running cryptography on web pages:

  • Electronic signature creation and verification;
  • Encrypting and decrypting files and CRY-packages.

Cryptographic service:

  • works with any browser with JavaScript support;
  • works with browsers with default settings (including Internet Explorer);
  • provides unified access control (when working with plugins the set of available rights depends on the settings of a specific browser).
