+ * sha1.c
+ *
+ * Description:
+ * This file implements the Secure Hashing Algorithm 1 as
+ * defined in FIPS PUB 180-1 published April 17, 1995.
+ *
+ * The SHA-1, produces a 160-bit message digest for a given
+ * data stream. It should take about 2**n steps to find a
+ * message with the same digest as a given message and
+ * 2**(n/2) to find any two messages with the same digest,
+ * when n is the digest size in bits. 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
+ * uses <stdint.h> (included via "sha1.h" to define 32 and 8
+ * bit unsigned integer types. If your C compiler does not
+ * support 32 bit unsigned integers, this code is not
+ * appropriate.
+ *
+ * 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 the size of an 8-bit character.
