Do you know what is the secret and p size used in TLS?

Thanks for the answer. So 512-bit secret size is good, right? PS: I'll use only HKDF and not AES-CTR!

comment HMAC vs Encrypted Hash
I definitely have to develop my own protocol because of some particular needs... So what is best to use? AES(Data) + HMAC(AES(Data)) or AES(Data + HMAC(AES(Data))) ? Thanks

PS: AES will work in CBC mode...

comment HMAC vs Encrypted Hash
OK... How much long should the hmac key be for SAH1 and SHA256 respectly? Using a key for received messages (client_read_hmac_key) and another key for sent messages (client_write_hmac_key) should allow me to use the same AES key for both sending and receiving because using two different keys for HMAC mitigates the replay attack of a client command to the server. Am I right?
