- *
- *  Description:
- *      This class implements the Secure Hashing Standard as defined
- *      in FIPS PUB 180-1 published April 17, 1995.
- *
- *      The Secure Hashing Standard, which uses the Secure Hashing
- *      Algorithm (SHA), produces a 160-bit message digest for a
- *      given data stream.  In theory, it is highly improbable that
- *      two messages will produce the same message digest.  Therefore,
- *      this algorithm can serve as a means of providing a "fingerprint"
- *      for a message.
- *
- *  Portability Issues:
- *      SHA-1 is defined in terms of 32-bit "words".  This code was
- *      written with the expectation that the processor has at least
- *      a 32-bit machine word size.  If the machine word size is larger,
- *      the code should still function properly.  One caveat to that
- *      is that the input functions taking characters and character arrays
- *      assume that only 8 bits of information are stored in each character.
- *
- *  Caveats:
- *      SHA-1 is designed to work with messages less than 2^64 bits long.
- *      Although SHA-1 allows a message digest to be generated for
- *      messages of any number of bits less than 2^64, this implementation
- *      only works with messages with a length that is a multiple of 8
- *      bits.
