Hi Team,
I am trying to implement mac-then-encrypt for aes_cbc_hmac_sha1
combined cipher. From the code i could understand that the first 16
bytes were being used as explicit IV while decrypting and the hmac is
done for 13 bye AAD and 16 byte Fin record in finish message.
Which RFC/section explains this in detail?
For TLS 1.2, this is RFC5246 Section 6.2.3.2
Note that each version of TLS makes arbitrary changes to the record
encryption.
Enjoy
Jakob
