DESCRIPTION:
    The original PDF document describing the SHA-256, SHA-384, and
    SHA-512 hashes provided sample output only for SHA-256.  The
    SHA-224 sample output comes from R. Housley's IEATF PKIX Working
    Group draft document dated December 2003 titled "A 224-bit
    One-way Hash Function: SHA-224".  NIST's FIPS 180-2 document
    provided output for SHA-1.  The output for SHA-384 and SHA-512
    came from my own implementation.
