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.
