getAlgorithmName
public java.lang.String getAlgorithmName()
Description copied from interface:Digest
return the algorithm name- Specified by:
getAlgorithmName
in interfaceDigest
- 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.- Specified by:
getDigestSize
in interfaceDigest
- Returns:
- the size, in bytes, of the digest produced by this message digest.
-
getByteLength
public int getByteLength()
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.
-
update
public void update(byte in)
Description copied from interface:Digest
update the message digest with a single byte.
-
update
public void update(byte[] input, int inOff, int len)
Description copied from interface:Digest
update the message digest with a block of bytes.
-
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.
