Class: Crypt_RC42

[line 68]
RC4 stream cipher routines implementation.

in PHP5(!) based on code written by Damien Miller <djm@mindrot.org> This class BREAKS COMPABILITY with earlier PHP 4 versions of the RC4 class. PHP 4 versions are available at http://pear.php.net/package/Crypt_RC42, download version 1.x

Basic usage of this class

 $key = "pear";

 $message = "PEAR rulez!";
 
 $rc4 = new Crypt_RC42();
 $rc4->key($key);
 echo "Original message: $message <br />\n";
 
 $message = $rc4->encrypt($message);
 $safe_codedmessage = base64_encode($message);
 echo "Encrypted message: $safe_codedmessage <br />\n";
 
 $message $rc4->decrypt($message);
 echo "Decrypted message: $message <br />\n";

Another example how the class can be used

 $origmessage = "PEAR Rulez!";

 
 $rc4 = new Crypt_RC42("pear");
 $codedmessage = $rc4->encrypt($origmessage);
 $safe_codedmessage = base64_encode($codedmessage);
 echo "Encrypted message: $safe_codedmessage <br />\n";

Note: The encrypted output is binary, and therefore cannot be properly displayed in shell or a browser. If you would like to display, please use the base64_encode function as above.
