SHA256, provided by TBS Internet since 2008, will in the coming few years replace SHA1. RSA2013 presentation SHA2. NIST chose Keccak anyway, despite it's cons, for it's pro: the dissimilarity to SHA-2 (which is still based on the "old" MD-5). There are also truncated versions of each standard, known as SHA-224, SHA-384, SHA-512/224 and SHA-512/256. But what is SHA? SHA-3 (Secure Hash Algorithm This would have provided at least a SHA3-224 and SHA3-256 with the same preimage resistance as their SHA-2 predecessors, but SHA3-384 What is the relationship between “SHA-2” and “SHA-256 SHA2-256 etc. The SHA-1 Hash encryption algorithm specifies a Secure Hash Algorithm, On the surface, SHA1 and MD5 look pretty similar.
