Constructor Detail

MD5Digest

public MD5Digest()
Standard constructor


MD5Digest

public MD5Digest(MD5Digest t)
Copy constructor. This will copy the state of the provided message digest.

Method Detail

getAlgorithmName

public java.lang.String getAlgorithmName()
Description copied from interface: Digest
return the algorithm name

Returns:
the algorithm name

getDigestSize

public int getDigestSize()
Description copied from interface: Digest
return the size, in bytes, of the digest produced by this message digest.

Returns:
the size, in bytes, of the digest produced by this message digest.

processWord

protected void processWord(byte[] in,
                           int inOff)
Specified by:
processWord in class GeneralDigest

processLength

protected void processLength(long bitLength)
Specified by:
processLength in class GeneralDigest

doFinal

public int doFinal(byte[] out,
                   int outOff)
Description copied from interface: Digest
close the digest, producing the final digest value. The doFinal call leaves the digest reset.

Parameters:
out - the array the digest is to be copied into.
outOff - the offset into the out array the digest is to start at.

reset

public void reset()
reset the chaining variables to the IV values.

Specified by:
reset in interface Digest
Overrides:
reset in class GeneralDigest

processBlock

protected void processBlock()
Specified by:
processBlock in class GeneralDigest
