DavidSchinazi commented on this pull request. > +Before a TLS ciphersuite can be used with QUIC, a header protection algorithm +MUST be specified for the AEAD used with that ciphersuite. This document +defines algorithms for AEAD_AES_128_GCM, AEAD_AES_128_CCM, AEAD_AES_256_GCM, +AEAD_AES_256_CCM (all AES AEADs are defined in {{!AEAD=RFC5116}}), and +AEAD_CHACHA20_POLY1305 {{!CHACHA=RFC8439}}. + + +### Header Protection Sample {#hp-sample} + +The header protection algorithm uses both the header protection key and a sample +of the ciphertext from the packet Payload field. + +The same number of bytes are always sampled, but an allowance needs to be made +for the endpoint removing protection, which will not know the length of the +Packet Number field. In sampling the packet ciphertext, the Packet Number field +is assumed to be 4 bytes long (its maximum possible encoded length), unless I would be inclined to disallow TLS_AES_128_CCM_8_SHA256 in QUIC but either way padding the payload is a viable solution -- You are receiving this because you are subscribed to this thread.
