Enables use of CAdES-format electronic digital signatures (ЭЦП) in Chrome/Edge/Firefox by bridging web pages to the locally installed CryptoPro native messaging host, since NPAPI/PPAPI plugin APIs are no longer supported in modern browsers

1. User installs the extension along with the CryptoPro native messaging host on their OS. 2. When a web page loads the cadesplugin JS library, the content script detects it and establishes a communication channel. 3. The web page sends signing/verification requests via window.postMessage. 4. Content script relays requests to background.js, which forwards them to the native host via native messaging. 5. Results are returned back through the chain to the web page.

目标用户: Russian users and organizations requiring CAdES digital signatures in the browser / Users of CryptoPro cryptographic software suite / Government and enterprise users working with electronic document signing

Cannot inspect the native messaging host (ru.cryptopro.nmcades) which is a separate OS-level application - CryptoPro CSP may have its own licensing
The extension itself is clearly free but the underlying CryptoPro cryptographic software suite may require paid licenses for commercial use
No privacy policy URL available to verify data handling practices
