I'm having some problem on using 3DES encryption in PHP 5.2.9.

I have followed all the steps to configure mcrypt in php.ini file.I have removed the ; from the extensions extension=php_mcrypt.dll and i also made a copy/paste of libmcrypt.dll from the folder php to C:/WINDOWS/system32/.I have restarted the Webserver Apache but when i tried to encrypt data using encrypt and decrypt function created in php code i'm having the error message below:Call to undefined function mcrypt_module_open() .

 

Could you kindly help me to resolve this problem?

 

Below you will find the code that i used :

 

</html>

<head><title>Encryption</title>

</head>

<body>

 

<form name=form method=post action='encrypt.php'>

<table align=center>

<TR><TD>Source Text:</TD><TD><input type=text name=input value=<?php echo $_REQUEST['input']; ?>></TD></TR>

<TR><TD>Key:</TD><TD><input type=text name=key value=<?php echo $_REQUEST['key']; ?>></TD></TR>

</table>

<input type=submit>

</form>

<?php

if(!empty($_REQUEST['input'])){

  $encrypted=encrypt($_REQUEST['input']);

  $decrypted=decrypt($encrypted);

 

  echo "Encrypted : '$encrypted' Decrypted: '$decrypted' <BR>";

}

 

$key = $_REQUEST['key'];

 

//Encrypt Function

function encrypt($encrypt) {

  global $key;

  $iv = mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB), MCRYPT_RAND);

  $passcrypt = mcrypt_encrypt(MCRYPT_RIJNDAEL_256, $key, $encrypt, MCRYPT_MODE_ECB, $iv);

  $encode = base64_encode($passcrypt);

return $encode;

}

 

//Decrypt Function

function decrypt($decrypt) {

  global $key;

  $decoded = base64_decode($decrypt);

  $iv = mcrypt_create_iv(mcrypt_get_iv_size(MCRYPT_RIJNDAEL_256, MCRYPT_MODE_ECB), MCRYPT_RAND);

  $decrypted = mcrypt_decrypt(MCRYPT_RIJNDAEL_256, $key, $decoded, MCRYPT_MODE_ECB, $iv);

return $decrypted;

}

 

?>

 

</body>

</html>
