Method Detail

getAlgorithmName

public java.lang.String getAlgorithmName()

Description copied from interface: Digest

return the algorithm name

Specified by:

getAlgorithmName in interface Digest

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 interface Digest

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 interface ExtendedDigest

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.

Specified by:

update in interface Digest

Parameters:

in - the input byte to be entered.

update

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

Description copied from interface: Digest

update the message digest with a block of bytes.

Specified by:

update in interface Digest

Parameters:

input - 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[] output,
                   int outOff)

Description copied from interface: Digest

close the digest, producing the final digest value. The doFinal call leaves the digest reset.

Specified by:

doFinal in interface Digest

Parameters:

output - 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()

Description copied from interface: Digest

reset the digest back to it's initial state.

Specified by:

reset in interface Digest
