一、AES-CBC 加密方案

<?php
$privateKey = "1234567812345678";
$iv = "1234567812345678";
$data = "Test String";

//加密
$encrypted = mcrypt_encrypt(MCRYPT_RIJNDAEL_128, $privateKey, $data, MCRYPT_MODE_CBC, $iv);
echo(base64_encode($encrypted));
echo '<br/>';

//解密
$encryptedData = base64_decode("2fbwW9+8vPId2/foafZq6Q==");
$decrypted = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $privateKey, $encryptedData, MCRYPT_MODE_CBC, $iv);
echo($decrypted);
?>

二、DES加密方案

//加密  
function encrypt($str, $key="12345678"){
    $block = mcrypt_get_block_size(MCRYPT_DES, MCRYPT_MODE_ECB);
    $pad = $block - (strlen($str) % $block);
    $str .= str_repeat(chr($pad), $pad);
    $data = mcrypt_encrypt(MCRYPT_DES, $key, $str, MCRYPT_MODE_ECB);
    $ret = base64_encode($data);
    return $ret;
}

//解密 
function decrypt($str, $key="12345678"){
    $str = base64_decode($str);
    $str = mcrypt_decrypt(MCRYPT_DES, $key, $str, MCRYPT_MODE_ECB);
    $block = mcrypt_get_block_size(MCRYPT_DES, MCRYPT_MODE_ECB);
    $pad = ord($str[($len = strlen($str)) - 1]);
    return substr($str, 0, strlen($str) - $pad);
}
