All Implemented Interfaces:

java.lang.Cloneable

public class RipeMd160
extends AbstractMessageDigest

This class implements the RipeMd160 message digest algorithm. It produces a 160 bit digest (hence the name) and can be used as an alternative to SHA-1. Both algorithms are generally considered to be equally strong, the speed is almost identical as well. The name of the algorithm to use with getInstance() is RIPEMD160.

For a specification of the algorithm see Fast Software Encryption, LCS 1039, Springer Verlag, 1996, pp. 71-82. Also available online from http://www.esat.kuleuven.ac.be/cosic/cosic.html.

Constructor Detail

RipeMd160

public RipeMd160()

Creates a new RipeMd160 message digest object. Applications do not use this constructor. They shall use

 MessageDigest.getInstance("RIPEMD160");
 

for creating a messageDigest object.

See Also:

MessageDigest.getInstance(java.lang.String)

Method Detail

clone

public java.lang.Object clone()

Returns a clone of this RipeMd160 Object.

Overrides:

clone in class AbstractMessageDigest

Returns:

a clone of this RipeMd160 Object

engineReset

protected void engineReset()

SPI: Resets this RipeMd160 message digest object for being supplied with new data.

This method is called by engineDigest 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.

Specified by:

engineReset in class AbstractMessageDigest
