I want to add RSA and RC5 functions into the 3ui's wtls package. I use the fake_wtls
(as client) and wtls_box(as server) to test my modification. When two sides are
compute the master_secret, calling the function in Openssl-0.9.5a
HMAC(EVP_sha1(),secret,secret_len,seed,seed_len,a,&t_len);
the "secret" and "seed" are same in two sides, but the results of "a" are different.
And, if I run the client and server another time, the results of "a" are different
with the last time.
Who can tell me why?
