-/**
- * SHA1 Encoding Class
- *
- * Purpose: Provides 160 bit hashing using The Secure Hash Algorithm
- * developed at the National Institute of Standards and Technology. The 40
- * character SHA1 message hash is computationally infeasible to crack.
- *
- * This class is a fallback for servers that are not running PHP greater than
- * 4.3, or do not have the MHASH library.
- *
- * This class is based on two scripts:
- *
- * Marcus Campbell's PHP implementation (GNU license)
- * http://www.tecknik.net/sha-1/
- *
- * ...which is based on Paul Johnston's JavaScript version
- * (BSD license). http://pajhome.org.uk/
- *
- * I encapsulated the functions and wrote one additional method to fix
- * a hex conversion bug. - Rick Ellis
