+ *
+ * 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.
