1) dans les sources openssl il y a un fichier client.c ou un truc du genre, très clair

2) Differences between SSLv3 and TLS
SSLv3 is the very similar to TLS with a few minor differences, among which are
1. the version number of TLS is 3.1 and SSL is 3.0
2. slightly different MAC schemes
3. different pseudorandom functions
4. additional alert codes in TLS
5. TLS does not support Fortezza while SSLv3 does
6. SSLv3 has additional client certificate types for ephemeral Diffie Hellman and Fortezza schemes that TLS does not
7. hashes calculated differently over the certificate verify handshake message
8. different calculation of the master secret
9. padding lengths. In SSLv3, the padding length is the minimum required to obtain a multiple of the cipher's block length while TLS allows any padding length that results in a multiple of the block length
