Description:
------------
My decrypting routines now fail to decrypt and in fact seem to return the encrypted value.

Reproduce code:
---------------
function encrypt_pwd($password)
{
/* Return encrypted password */
	global $config;
	$password = trim($password);
	$iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_ECB);
	$key = mhash(MHASH_MD5,substr($config['pass_phrase'], 0, mcrypt_get_key_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_ECB)));
 error_log("EP===".$password."===");
 error_log("EK===".$key."===");
	$iv = mcrypt_create_iv($iv_size, MCRYPT_RAND);
	$enc_pwd = mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $key, $password, MCRYPT_MODE_ECB, $iv);
 error_log("EE===".$enc_pwd."===");
	return $enc_pwd;
}

function decrypt_pwd($password)
{
/* Return decrypted password */
	global $config;
	$iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_ECB);
	$key = mhash(MHASH_MD5,substr($config['pass_phrase'], 0, mcrypt_get_key_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_ECB)));
 error_log("DP===".$password."===");
 error_log("DK===".$key."===");
	$iv = mcrypt_create_iv($iv_size, MCRYPT_RAND);
	$dec_pwd = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $key, $password, MCRYPT_MODE_ECB, $iv);
 error_log("DD===".trim(chop($dec_pwd))."===");
	return trim(chop($dec_pwd));
}



Expected result:
