The SHA module allows you to use the NIST SHA message digest
algorithm from within Perl programs.
The final message digest value is returned by the digest
operation as a 20-byte binary string. This operation delivers
the result of operations since the last new or reset
operation. Once the operation has been performed, the context
must be reset before being used to calculate another digest
value.
