正如IRC所讨论的那样,create_rsa_key问题的答案由 https://***.com/a/29589818/37923 - 这不是为了这样工作。
pcszPassphrase意味着是保护私钥的密码/短语。它将由用户提供,但不是要求。
The main problem is that I'm quite new to C, and the OpenSSL documentation is not clear enough for me, I've tried using Reading and writing rsa keys to a pem file in C, but I don't quite understand it. For example, how does the create_rsa_key()
function creates both the private and the public? And where does pCipher
come from? And what's the point of the pcszPassphrase
?
I'll explain as if it was some sort of pseudocode, this is what I want to do, and the parts in bold are those I don't know how to do it:
Basically I know how to handle AES encryption/decryption and the communication protocol, they're already implemented anyway, my issue is RSA, and I need hex format not base64 or pem as I'm working with sockets and sending and storing as binary data.
As discussed on IRC, the answer to the create_rsa_key question is addressed by https://***.com/a/29589818/37923 - it's not meant to work that way.
pcszPassphrase is meant to be the password/phrase to protect the private key. It would be provided by the user, but isn't a requirement.
