Apr 10, 2019 · A cipher suite is a combination of authentication, encryption, and message authentication code (MAC) algorithms. They are used during the negotiation of security settings for a TLS/SSL connection as well as for the transfer of data. The following are examples of what algorithms a cipher suite may use. Weak Elliptic Curves; RSA Key Exchange; Static Diffie-Hellman (DH, ECDH) Because the structure of 1.3 cipher suites is different from its predecessors’, TLS 1.3 cipher suites will not be interchangeable with older TLS versions. In today's day and age, hardening your servers and removing older or weak cipher suites is becoming a major priority for many organizations. Software suites are available that will test your servers and provide detailed information on these protocols and suites.

Dec 12, 2019 · SSL Cipher is an encryption algorithm, which is used as a key between two computers over the Internet. Data encryption is the process of converting plain text into secret ciphered codes. It’s based on your web server SSL Cipher configuration and strong protocol that allows data encryption to take place.
