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.

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 ...

Mozilla was the latest to fall in line, yesterday asking Certificate Authorities and websites to upgrade certificates to SHA-256, SHA-384 or SHA-512, all exponentially stronger mathematically than ...

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).

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.

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 ...

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 ...
