Method Detail

reset

public void reset()

SPI: Resets this MD2 message digest object for being supplied with new data.

This method is called after the actual hash computation has been finished to automatically reset the message digest object for being supplied with new data for starting a new hash computation.

Overrides:

reset in class MessageDigest

clone

public Object clone()

Returns a clone of this MD2 Object.

Overrides:

clone in class MessageDigest

Returns:

a clone of this MD2 Object

digest

public int digest(byte[] output,
                  int offset)

SPI: Returns the result of this hash computation and resets this MD2 message digest object for being supplied with new data to be hashed.

Overrides:

digest in class MessageDigest

Returns:

a byte array holding the calculated hash value

compress

protected void compress(byte[] input,
                        int offset)

The heart of MD2.

Overrides:

compress in class MessageDigest

getEncodedDigestInfo

public byte[][] getEncodedDigestInfo()

Description copied from class: MessageDigest

Returns the pregenerated ASN1 encoding of the DigestInfo structure for the corresponding digest algorithm, see . The digest value is of course NOT included. The two dimensional array cotains the enconding with (index = 0) and without the ASN1 parameter NULL (index = 1).

Overrides:

getEncodedDigestInfo in class MessageDigest

Following copied from class: iaik.me.security.MessageDigest

Returns:

a two dimensional byte array containing the digestinfo encodings
