Class Hash160

java.lang.Object
  org.bitcoin.x6763.crypto.digest.Hash160

public class Hash160
extends java.lang.Object

The Hash160 class provides methods for hashing data first with SHA-256, and feeding that result into the RIPEMD-160 hash.

There are two ways this class can be used. The first way is to use the static hash method, which will internally instantiate the SHA256 and RIPEMD160 classes on each call:

 byte[] data = new String("abc").getBytes();
 byte[] hash = Hash160.hash(data);
 
 

The second way is to instantiate a Hash160 object and use the hashBytes instance method. The Hash160 object will then reuse the same SHA256 and RIPEMD160 objects for each call to hashBytes:

 Hash160 hash160 = new Hash160();
 
 byte[] data1 = new String("def").getBytes();
 byte[] hash1 = hash160.hashBytes(data1);
 
 byte[] data2 = new String("ghi").getBytes();
 byte[] hash2 = hash160.hashBytes(data2);
