getAlgorithm()
Returns the name of this digest ("MD4").
int
getBlockLength()
Returns the block length of the digest in bytes.
int
getDigest(byte[] buffer,
int offset,
boolean resetDigest)
Inserts the digest of all the input data since the last reset
into the specified buffer at the given offset.

Most digest algorithms are iterated hash functions, and thus process the input data in blocks.
Some primitives, like HMAC are sensitive to this block length.

getDigest
public int getDigest(byte[] buffer,
int offset,
boolean resetDigest)
offset - The offset, or initial bit position, to store the data at within the array.
resetDigest - if true, then the digest is reset.
Returns:
An integer representing the number of bytes written to the buffer.
