update
public void update(byte in)
Deprecated.Description copied from interface:Digest
update the message digest with a single byte.
-
update
public void update(byte[] input, int inOff, int len)
Deprecated.Description copied from interface:Digest
update the message digest with a block of bytes.

Deprecated.
-
setBytes
protected void setBytes(long w, byte[] bytes, int inOff)
Deprecated.

protected void setBytes(long w, byte[] bytes, int inOff, int n)
Deprecated.
-
getAlgorithmName
public java.lang.String getAlgorithmName()
Deprecated.Description copied from interface:Digest
return the algorithm name- Specified by:
getAlgorithmName
in interfaceDigest
- Returns:
- the algorithm name
-
doOutput
public int doOutput(byte[] output, int outOff, int outLen)
Deprecated.Description copied from interface:Xof
Start outputting the results of the final calculation for this digest. Unlike doFinal, this method will continue producing output until the Xof is explicitly reset, or signals otherwise.
-
doFinal
public int doFinal(byte[] output, int outOff, int outLen)
Deprecated.Description copied from interface:Xof
Output the results of the final calculation for this digest to outLen number of bytes.
-
getByteLength
public int getByteLength()
Deprecated.Description copied from interface:ExtendedDigest
Return the size in bytes of the internal buffer the digest applies it's compression function to.- Specified by:
getByteLength
in interfaceExtendedDigest
- Returns:
- byte length of the digests internal buffer.
-
reset
public void reset()
Deprecated.Description copied from interface:Digest
reset the digest back to it's initial state.
-
p
protected void p(int nr)
-
getDigestSize
public int getDigestSize()
Description copied from interface:Digest
return the size, in bytes, of the digest produced by this message digest.- Specified by:
getDigestSize
in interfaceDigest
- Returns:
- the size, in bytes, of the digest produced by this message digest.
-
doFinal
public int doFinal(byte[] output, int outOff)
Description copied from interface:Digest
close the digest, producing the final digest value. The doFinal call leaves the digest reset.

squeeze
protected void squeeze(byte[] output, int outOff, int len)
-
hash
