[Ipsec-tools-devel] Does OpenSsl truncate the HMAC_SHA1 to 96 bits

[Prashant K. <pki...@ya...>]

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.
