AES-GCM Algorithm is missing tag properties for authentication tag

State:

CLOSED

Product:

Web Cryptography API

Raised by:

Description:

Pickup a mail list discussion issue so it is not lost, and I am currently trying to get something coded.

Current API does not have a separate tag field for input and output. While I personally field this is the best way to proceed, all that is required is that the text be more explicit about how tags are dealt with for processing. If tags are appended to the cipher text that needs to be stated and the description for tagLength be updated (it is not the actual length for decrypt). Otherwise if we are going to have an output tag field that is explicit then this needs to be documented.
