问题 I have following values: client-random bytes server-random bytes pre-master secret I don't want to use features like SSL , SSL_CTX etc. What I want is, just I have three numbers, I want to calculate master-number from them. How do I calculate master-key in c using OpenSSL? Is there any function in OpenSSL C library for PRF specified in RFCs? Thank You. 回答1: JKJS int master_secret(unsigned char *dest,int len,unsigned char *pre_master_secret,int pms_len,unsigned char *label,unsigned char *seed

问题 I'm working on communication nodejs -> c# server. I need to secure connection between them so I chode ECDiffieHellman as the key exchange mechanism (nodejs supports it). I had some problem with it... Just my lack of knowledge so I've made my lesson and now I can generate and export keys as base64 and nodejs have no problem with accepting c# key but on the other side c# ... won't even take his own key ... error System.Security.Cryptography.CryptographicException: 'The parameter is incorrect.'
