Requires navigator based on Chromium
Tested the October 15, 2024 with :
– Microsoft Edge Version 130.0.2849.56 (Version officielle) (64 bits)

Note:

Version 2 of the manifest for all Chromium-based browsers (Chrome, Edge, Brave, Opera, etc.) enables automatic decryption of files via the DataShielder NFC Hardware Security Module (HSM). This version ensures seamless integration of the decryption process with NFC technology, providing a safe and efficient method to handle encrypted files. On the other hand, the V3 manifest currently published on the Chrome Web Store and Edge Addons works, but to decrypt the files, you will have to manually select the appropriate decryption key.
