+ * SHA-224, SHA-256, SHA-384 and SHA-512 interface.
+ *
+ * SHA-256 has been published in FIPS 180-2, now amended with a change
+ * notice to include SHA-224 as well (which is a simple variation on
+ * SHA-256). SHA-384 and SHA-512 are also defined in FIPS 180-2. FIPS
+ * standards can be found at:
+ *    http://csrc.nist.gov/publications/fips/
