Package	calista.hash
Class	public final class CRC32
Inheritance	CRC32 Object

A cyclic redundancy check (CRC) is a non-secure hash function designed to detect accidental changes to raw computer data, and is commonly used in digital networks and storage devices such as hard disk drives. This algorithm is used in the GZIP file format specification version 4.3 defines in the RFC 1952.

Example :

     package examples 
     {
         import calista.hash.CRC32;
         
         import flash.display.Sprite;
         import flash.utils.ByteArray;
         
         public class CRC32Example extends Sprite 
         {
             public function CRC32Example()
             {
                 var bytes:ByteArray = new ByteArray() ;
                 bytes.writeUTFBytes("hello world") ;
                 
                 var sum:uint = CRC32.checkSum(bytes) ;
                 
                 trace("CRC32 : " + sum + " 0x" + sum.toString( 16 ).toUpperCase() ) ; // CRC32 : 222957957 0xD4A1185
             }
         }
     }
