MD5SumValue - Storage for a MD5Sum
MD5Summation - MD5 Message Digest Algorithm.
This is a C++ interface to a set of MD5Sum functions. The class can
store a MD5Sum in 16 bytes of memory.
A MD5Sum is used to generate a (hopefully) unique 16 byte number for a
block of data. This can be used to gaurd against corruption of a file.
MD5 should not be used for tamper protection, use SHA or something more
secure.
There are two classes because computing a MD5 is not a continual
operation unless 64 byte blocks are used. Also the summation requires an
extra 18*4 bytes to operate.
