This packet is build with SSL Record Header (2 bytes) and with SSL Handshake client_hello packet (rest of data). SSL3 form of this packet will be: 16 03 00 00 2f 01 00 00-2b 03 00 46 cd dd 9e ab 47 d3 b4 6a e6 3a 00 0d-c1 3f e3 9c 17 a6 c3 3d 8d 89 63 10 6b 55 bf bd-05 4c fa 00 00 04 00 35 00 2f 01 00 which means: 16 - SSL3/TLS1 handshake packet 03 00 - SSL3 proposition in Record Layer 00 2f - length of handshake data 01 - client_hello packet 00 00-2b length of client_hello data 03 00 - SSL3 proposition in Handshake layer 46 cd dd 9e ab 47 d3 b4 6a e6 3a 00 0d-c1 3f e3 - client_random (32 bytes) 9c 17 a6 c3 3d 8d 89 63 10 6b 55 bf bd-05 4c fa 00 - session id len 00 04 - cipher suite len 00 35 - first cipher suite (rsa_aes256_sha1) 00 2f - second cipher suite (rsa_aes128_sha1) 01 - "compression suite length" 00 - no compression Here first 5 bytes are SSL Record and rest are SSL handshake.
