The Skein-512 variant can hash data at 6.1 clock cycles per byte on a 64-bit CPU. Schneier estimates that this is almost twice as fast as SHA-512.

SHA-2 is actually a set of cryptographic hash functions (SHA-224, SHA-256, SHA-384, SHA-512) in the MD (message digest) algorithm design.

Perhaps anticipating the news, the National Institute of Standards and Technology issued a recommendation earlier this month that developers move to SHA-256 and SHA-512 algorithms by 2010. “NIST might ...

In 1992, he improved on MD4 and developed another hash function: MD5. In 1993, the National Security Agency published a hash function very similar to MD5, called the Secure Hash Algorithm (SHA).

At the same time, PGP engineers began implementing a shift from SHA-1 to the stronger algorithms (SHA-256 and SHA-512) while preserving interoperability with existing software. The upcoming releases ...

SHA Family of Cores Original SHA-224, SHA-256, SHA-384, and SHA-512 cores have implemented the corresponding versions of the SHA algorithm, leaving the HMAC implementation in the external wrapper. The ...

OpenSSH went on to point out that there are better alternatives out there, including RFC8332 RSA SHA-2 signature algorithms rsa-sha2-256/512.

NIST had received 63 submissions since putting out an to find a successor to SHA-2. SHA-2 is actually a set of cryptographic hash functions (SHA-224, SHA-256, SHA-384, SHA-512) in the MD (message ...
