- 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 guard 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.
