* Details: Implementation of the SHA-256 hashing algorithm.
|

SHA-256 is one of the three algorithms in the SHA2
|
||||
specification. The others, SHA-384 and SHA-512, are not
|
||||
offered in this implementation.
|
||||
Algorithm specification can be found here:
|
||||
* http://csrc.nist.gov/publications/fips/fips180-2/fips180-2withchangenotice.pdf
|
||||
This implementation uses little endian byte order.
