SHA-2 (Secure Hash Algorithm 2) is a set of cryptographic hash functions designed by the United States National Security Agency (NSA) and first published in 2001. They are built using the Merkle–Damgård structure, from a one-way compression function itself built using the Davies–Meyer structure from a (classified) specialized block cipher.
Supported SSL/TLS Protocols and Ciphers for Communication Between CloudFront and Your Origin If you choose to require HTTPS between CloudFront and your origin, you can decide which SSL/TLS protocol to allow for the secure connection, and then pick any supported cipher for CloudFront (see the following tables) to establish an HTTPS connection to your origin. For WolfSSL, valid examples of cipher lists include ´ECDHE-RSA-RC4-SHA´, 'AES256-SHA:AES256-SHA256', etc. The application does not have to keep the string around after setting this option. DEFAULT. NULL, use internal default PROTOCOLS. All TLS based protocols: HTTPS, FTPS, IMAPS, POP3S, SMTPS etc. EXAMPLE Cipher Suites. We publish a public repository of our SSL/TLS configurations on GitHub, and changes can be found in commit history.Please note that Cloudflare no longer supports RC4 cipher suites or SSLv3.

TLS Cipher String Cheat Sheet¶ Introduction¶. This article is focused on providing clear and simple examples for the cipher string. They are based on different scenarios where you use the Transport Layer Security (TLS) protocol.
ecdh-ecdsa-aes256-sha ECDH-ECDSA-AES128-SHA Although these are the permitted cipher suites, if your TLS server does not deal with large variety of different platforms and clients, it is recommended that only a small subset of these algorithms be used. SHA-2 is a hashing algorithm whereas AES is an encryption algorithm. SHA-2 is generally used for Integrity check AES used for Encryption and Decryption (for Confidentiality) SHA-2 is one way function AES is two way function Hashing Algorithm
