Method Details

getAlgorithmName

public String getAlgorithmName()

Description copied from interface: Digest

return the algorithm name

Returns:

the algorithm name

update

public void update(byte in)

Description copied from interface: Digest

update the message digest with a single byte.

Parameters:

in - the input byte to be entered.

update

public void update(byte[] in,
 int inOff,
 int len)

Description copied from interface: Digest

update the message digest with a block of bytes.

Parameters:

in - the byte array containing the data.

inOff - the offset into the byte array where the data starts.

len - the length of the data.

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.
