Description of mode and format

• Browser SubtleCrypto for AES provides only GCM, CBC, CTR and not ECB, CFB, OFB etc. (avoiding poor use). If you want another mode, use OpenSSL/ service library.
• The secret text is available for Hex / Base64 / Base64URL, which corresponds to the CyberChef, API, JWT, etc.; both sides of the decryption must be selected in the same format.
• AES-GCM output is a continuous byte for "secret + authentication label " ; the whole of this tool is coded in the selected format and paste the whole paragraph when decrypted.

Annotations

• Web Crypto operates in a browser; GCM is encrypted to fit the default scene.
• When encrypted, IV will be left empty, and the tool will generate random IV and write to the top input box, which will be useful to reuse when decrypted.
• When decrypting, IV will be left empty at the full 0 vector (valid only when the other party uses the same agreement).
