clone
public Object clone()
Returns a copy of this MD object.
engineDigest
public byte[] engineDigest()
Completes the hash computation by performing final operations such
as padding. At the return of this engineDigest, the MD engine is
reset.
- the array of bytes for the resulting hash value.
engineReset
public void engineReset()
Resets this object disregarding any temporary data present at the
time of the invocation of this call.
engineUpdate
public void engineUpdate(byte b)
Continues an MD4 message digest using the input byte.
engineUpdate
public void engineUpdate(byte[] input,
int offset,
int len)
MD4 block update operation.
Continues an MD4 message digest operation, by filling the buffer,
transform(ing) data in 512-bit message block(s), updating the variables
context and count, and leaving (buffering) the remaining bytes in buffer
for the next update or finish.
input
- input blockoffset
- start of meaningful bytes in inputlen
- count of bytes in input block to consider
