Different algorithms for Header protection and packet protection #125

Open MaxF12 opened 2 years ago

MaxF12 commented 2 years ago

Do we need to keep this as an option or is it fine to just have the same for both?

GrumpyOldTroll commented 2 years ago

I think you're right, this should be the same TLS Cipher Suite for both, and we should remove the option to have different ones.

I read thru https://www.rfc-editor.org/rfc/rfc9001.html#section-5 again harder, particularly section 5.3, and it looks to me like the TLS cipher suite value uniquely determines both the AEAD algorithm and the header protection algorithm.
