php - AES 加密与 Node 和 PHP 不同

Question

我有两个脚本，都使用相同的算法来加密具有相同 key 和 IV 的字符串。但结果不同。 openssl_crypt 是否仍然使用与 Node 不同的填充方案，或者我是否遗漏了其他内容？

Node

const crypto = require('crypto');

var passphrase = '29486a7a37664140';
var iv = '76e69938cdf5bb64';
var text = '1234567890123456';

var cipher = crypto.createCipheriv('aes-128-ctr', passphrase, iv)
var crypted = cipher.update(text,'utf8','hex')
crypted += cipher.final('hex');

var result = crypted + ':' + iv;

console.log('crypted: (' + crypted.length + ' chars)', crypted);
// crypted: (32 chars) b94107e56900ec8270a847bbf457eaa6

PHP

<?php

$encrypt_method = "AES-128-CTR";
$passphrase = '29486a7a37664140';
$iv = '76e69938cdf5bb64';
$text = '1234567890123456';

$encrypted = openssl_encrypt( $text, $encrypt_method, $passphrase, 0, $iv );

echo 'crypted (' . strlen($encrypted) . ' chars): ' . $encrypted;
// crypted (24 chars): uUEH5WkA7IJwqEe79Ffqpg==
?>

Answer 1

好吧，好吧……愚蠢。编码问题:

更改我的 Node 部分以使用 bas64 有效

var cipher = crypto.createCipheriv('aes-128-ctr', passphrase, iv)
var crypted = cipher.update(text,'utf8','base64')
crypted += cipher.final('base64');
