    However, due to advances in technology, NIST plans to phase out of
    SHA-1 in favor of the larger and stronger hash functions (SHA-224,
    SHA-256, SHA-384 and SHA-512) by 2010. SHA-1 and the larger hash
    functions are specified in FIPS 180-2. For planning purposes by
    Federal agencies and others, note also that the use of other
    cryptographic algorithms of similar strength to SHA-1 will also be
    phased out in 2010.  SHA-1 and the stronger hash functions in FIPS
    180-2 are all NIST approved.
