Hello All,
 
While using the SHA1 based ciphers, does openssl truncate the HMAC calculated to 96 bits from 160 bits. Looking at the code looks like "tls_mac" function in "t1_enc.c" returns 160 bits. However, "tls1_final_finish_mac" function takes a buffer of length 96 bits. I am not sure when "tls_final_finish_mac" function is called.
 
Any help is appreciated.
 
Thanks,
Prashant.
