** -- Declare an MDstruct MD to hold the state of the digest
|
||||
** computation.
|
||||
** -- Initialize MD using MDbegin(&MD)
|
||||
** -- For each full block (64 bytes) X you wish to process, call
|
||||
** MD4Update(&MD,X,512)
|
||||
** (512 is the number of bits in a full block.)
|
||||
** -- For the last block (less than 64 bytes) you wish to process,
|
||||
** MD4Update(&MD,X,n)
|
||||
** where n is the number of bits in the partial block. A partial
|
||||
** block terminates the computation, so every MD computation
|
||||
** should terminate by processing a partial block, even if it
|
||||
** has n = 0.
|
||||
** -- The message digest is available in MD.buffer[0] ...

** MD.buffer[3]. (Least-significant byte of each word
