/* /* public domain sha256 implementation based on fips180-3 */
* public domain sha256 crypt implementation
*
* original sha crypt design: http://people.redhat.com/drepper/SHA-crypt.txt
* in this implementation at least 32bit int is assumed,
* key length is limited, the $5$ prefix is mandatory, '\n' and ':' is rejected
* in the salt and rounds= setting must contain a valid iteration count,
* on error "*" is returned.
