  DESCRIPTION
-   This file implements the Secure Hashing Algorithm 1 as
-   defined in FIPS PUB 180-1 published April 17, 1995.
-
-   The SHA-1, produces a 160-bit message digest for a given data
-   stream.  It should take about 2**n steps to find a message with the
-   same digest as a given message and 2**(n/2) to find any two
-   messages with the same digest, when n is the digest size in bits.
-   Therefore, this algorithm can serve as a means of providing a
-   "fingerprint" for a message.
