+ *  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.
