Hi, I am trying to tweak openssl-master client to test a tls1.3 enabled server. I want to club the client certificate, client key exchange , change cipher spec and certificate verify into single handshake message.( So that the record shows up as multiple handshake messages). OpenSSL Version : OpenSSL 1.1.1-dev xx XXX xxxx. After going through the code I understand the new tls1.3 implemented OpenSSL code is using WPACKET API to frame the records. I need help in understanding what the following functions do. I am new to the mailing list, thanks in advance. WPACKET_start_sub_packet_ WPACKET_allocate_bytes WPACKET_sub_allocate_bytes__ WPACKET_reserve_bytes WPACKET_start_sub_packet_len__ WPACKET_sub_memcpy__ Basically what does the word _sub_ mean in these functions and how do that differ from the non sub function say Difference between WPACKET_sub_memcpy__ and WPACKET_memcpy__ Please feel free to reply if something is not understandable. Sent from Mail for Windows 10 Thanks Sate. |
