Dhe diffie hellman
WebUsing Diffie-Hellman, however, a compromised private key won't instantly allow the attacker to decrypt all the prior captured cipher text. Which is why you'd want to use Diffie … WebClosed 6 years ago. I've been reading the same thing on a lot of websites: RSA is for communication using the public and private key for both the server and client, whereas Diffie-Hellman is just for exchanging the same secret key that will then be used for both encryption and decryption. But they both depend on the same math. Then I was ...
