Question related to TLS1.2 key computation function - PRF.

2012-12-10 Thread Tayade, Nilesh
Hi, As per RFC5246 - the TLS1.2 uses SHA256, SHA384 MAC. I would appreciate any pointers on how the PRF is implemented for TLS1.2. E.g. For TLS1.0, TLS1.1 - the HMAC-SHA1 is implemented as below. And SHA-1 uses 20bytes at a time. How many bytes SHA256 uses at a time? // First initialize the
