Detailed Description

This code implements the MD5 message-digest algorithm. The algorithm is due to Ron Rivest. This code was written by Colin Plumb in 1993, no copyright is claimed. This code is in the public domain; do with it what you wish.

The MD5 code was converted to an MD5 C++ object (MD50) by Jim Hipp, Sandia National Laboratories, in May of 2004. The code was modified Specifically for the PGL library and optimized to replace all "define" definitions with equivalent inlined function objects. The machine dependent byte reversal flag is called automatically at object construction to turn byte-reversal ON (big-endian) or OFF (little-endian). The flag can be manually set to either-endian format with the functions setBigEndian() or setLittleEndian().

The 32 byte hexadecimal string message digest is computed with any of the functions getMD5HashHex(...). The equivalent 16 byte binary message digest is returned with the functions getMD5BinHex(...).
