Question

我想更改给定数据库的所有密码。所有这些密码都是DES CBC PKCS7的密码，我有密钥和初始化向量。我使用下一个网页http://www.txtwizard.net/crypto来解密一个密码，结果是预期的（使用选项DES，CBC和PKCS7）。

键： RRZy0njZDzw =

iv： p / 34qWLNYfg =

纯文字 123123

加密文字 x541kJ4KvJo =

但是当用PHP编写的下一个代码我无法复制结果时：

<?php
    $key = "RRZy0njZDzw=";
    $iv = "p/34qWLNYfg=";
    $data = "123123";
    $cipher='DES-CBC';
    var_dump(openssl_get_cipher_methods());
    $encrypted = openssl_encrypt($data,$cipher, $key,OPENSSL_RAW_DATA,$iv);
    echo base64_encode($encrypted);
?>

此代码的输出为：

PHP Warning:  openssl_encrypt(): IV passed is 12 bytes long which is longer than the 8 expected by selected cipher, truncating in /home/sergio/Documents/DevEnvTest/siaf/aes2hash.php on line 7

Warning: openssl_encrypt(): IV passed is 12 bytes long which is longer than the 8 expected by selected cipher, truncating in /home/sergio/Documents/DevEnvTest/siaf/aes2hash.php on line 7

有没有办法获得与在线工具相同的字符串？

Answer 1

您需要从Base64解码您的密钥和IV：

$key = base64_decode("RRZy0njZDzw=");
$iv = base64_decode("p/34qWLNYfg=");

PHP OpenSSL使用DES-CBC算法加密意外输出
