SSL/TLS is the most widely used password communication method in the world. It uses cryptographic techniques such as symmetric password, message authentication code, public key password, digital signature, pseudo-random number generator and so on.
Cipher Suite
SSL/TLS provides a framework for password communication, a symmetric password used in SSL/TLS, a public key password, a digital signature, a one-way hash function, and other techniques that can be replaced if the cryptographic technology used is found to have weaknesses.
