Constructor Details

RIPEMD256Digest

public RIPEMD256Digest()
Standard constructor


RIPEMD256Digest

public RIPEMD256Digest(RIPEMD256Digest t)
Copy constructor. This will copy the state of the provided message digest.

Method Details

doFinal

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

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


getAlgorithmName

public String getAlgorithmName()
return the algorithm name
Specified by:
getAlgorithmName in interface Digest

Returns:
the algorithm name


getDigestSize

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

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


processBlock

protected void processBlock()
Overrides:
processBlock in interface GeneralDigest


processLength

protected void processLength(long bitLength)
Overrides:
processLength in interface GeneralDigest


processWord

protected void processWord(byte[] in,
                           int inOff)
Overrides:
processWord in interface GeneralDigest


reset

public void reset()
reset the chaining variables to the IV values.
Specified by:
reset in interface Digest
Overrides:
reset in interface GeneralDigest
