Thanks a lot Marek! I was making mistake at:
16 - SSL3/TLS1 handshake packet (was not including this) Now i understood the whole process completely, thanks to your guidance!. If there is any document or any such thing that has such details, it would be great if you could forward it to me. Thanks a lot again, it helped me a lot!

If you really want SSL2 client_hello here is example: 80 2f 01 03 01 00 06 00 00 00 20 00 00 35 00 00 2f 21 fc e5 6d 1e b9 49 78 55 ca fc 83 75 a4 75 82 5a 05 8a d2 51 8c bf dc 96 d2 fe 77 c1 60 8b 26 and this means: 80 - SSL2 handshake 2f - length of packet data (47 bytes) 01 - SSL2 client_hello packet 03 00 - SSL3 proposition 00 06 - cipher suite len 00 00 - session id len 00 20 - client_random/chalenge len (32 bytes) 00 00 35 - first cipher suite (rsa_aes256_sha1) 00 00 2f - second cipher suite (rsa_aes128_sha1) 21 fc e5 6d 1e b9 49-78 55 ca fc 83 75 a4 75 82 - client_random/challenge (to end) 5a 05 8a d2 51 8c bf-dc 96 d2 fe 77 c1 60 8b 26 This data send to server after will be properly understood. 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.
