解密nodejs代码

---

const crypto = 要求（'crypto'）；

常量算法 = 'AES';

常量键='9CT0qwtzUHLXlFTh0aLxk4qSQYAJ7texG8KDIZ0JSy8='；常量 iv = 'nG2rSrj1Ra9e03IStEBkdg==';

const decipher = crypto.createDecipheriv（算法，密钥，iv）；

---

错误 - IV 长度无效

Answer 1

不知道节点 js，但我已经在 PHP 中实现了这个 API，它对我有用。这可能对您有帮助。

$key = base64_decode('xxxxx');
$iv = base64_decode('xxxxxx');
$decryptedData = openssl_decrypt(file_get_contents($url), 'AES-256-CBC', $key, OPENSSL_RAW_DATA, $iv);

Answer 2

NodeJS 代码

const zlib = require('zlib');
const fs = require('fs');


let key = ((new Buffer.from((document.encryptionDetails.key), 'base64')));
let initializationVector = ((new Buffer.from((document.encryptionDetails.initializationVector), 'base64')));

let params = { method: `get`, url: `${document.url}`, responseType: 'stream', headers: { "Accept-Encoding": "gzip, deflate, br" }, encoding: null }

let documentResponse = await axios.request(params);

var decipher = crypto.createDecipheriv('aes-256-cbc', key, initializationVector);
decipher.setAutoPadding(false);
var gunzip = zlib.createGunzip();

            
const filePath = `/<path>/<fileName>`;

var writerOne = fs.createWriteStream(filePath);
if (document.compressionAlgorithm) {   (documentResponse.data).pipe(decipher).pipe(gunzip).pipe(writerOne); }
else { (documentResponse.data).pipe(decipher).pipe(writerOne); }

gunzip.on('error', error => { console.error(error.message || error); writerOne.close(); });
writerOne.on('error', error => { console.error(error.message || error); writerOne.close(); reject(`${error.message || error}`); });
writerOne.on('close', () => { resolve(filePath); });

这可能对您有帮助。

$key = base64_decode('xxxxx');
$iv = base64_decode('xxxxxx');
$decryptedData = openssl_decrypt(file_get_contents($url), 'AES-256-CBC', $key, OPENSSL_RAW_DATA, $iv);
 
if($compression_algorithm && $compression_algorithm == 'GZIP'){
    $decryptedData = gzdecode($decryptedData);
