25 | DESCRIPTION
|
---|
26 | This library provides the interface to SHA-256 secure hash algorithms.
|
---|
27 | SHA-256 performs processing on message blocks to produce a final hash digest
|
---|
28 | output. It can be used to hash a message, M, having a length of L bits,
|
---|
29 | where 0 <= L < 2^64.
