Question

我使用以下命令在命令行加密我的文件：

openssl aes-256-cbc -e -in test.env -out test.env.encrypted

然后尝试使用：

在node.js上解密

crypto    = require('crypto')
algorithm = 'aes-256-cbc'
password  = 'test'

fs = require 'fs'
decrypt = (text) ->
  decipher = crypto.createDecipher(algorithm, password)
  dec = decipher.update(text, 'hex', 'utf8')
  dec += decipher.final('utf8')
  dec

file = fs.readFileSync './test.env.encrypted', 'utf-8'

console.log decrypt file

但我收到以下错误：

TypeError: Bad input string at Decipher.update (crypto.js:168:26) at decrypt (/Users/h/tmp/encrypt_test/test.coffee:10:18) at Object.<anonymous> (/Users/h/tmp/encrypt_test/test.coffee:16:13) at Object.<anonymous> (/Users/h/tmp/encrypt_test/test.coffee:1:1) at Module._compile (module.js:569:30) at Object.CoffeeScript.run (/usr/local/lib/node_modules/coffeescript/lib/coffeescript/index.js:63:23) at compileScript (/usr/local/lib/node_modules/coffeescript/lib/coffeescript/command.js:265:29) at compilePath (/usr/local/lib/node_modules/coffeescript/lib/coffeescript/command.js:220:14) at Object.exports.run (/usr/local/lib/node_modules/coffeescript/lib/coffeescript/command.js:141:20) at Object.<anonymous> (/usr/local/lib/node_modules/coffeescript/bin/coffee:15:45) at Module._compile (module.js:569:30) at Object.Module._extensions..js (module.js:580:10) at Module.load (module.js:503:32) at tryModuleLoad (module.js:466:12) at Function.Module._load (module.js:458:3) at Function.Module.runMain (module.js:605:10) at startup (bootstrap_node.js:158:16) at bootstrap_node.js:575:3

我做错了什么？

UPDATE：

根据詹姆斯的说法，我现在正在发送一个＆＃34; hex＆＃34;字符串到我的解密函数：

crypto    = require('crypto')
algorithm = 'aes-256-cbc'
password  = 'test'

fs = require 'fs'

decrypt = (text) ->
  decipher = crypto.createDecipher(algorithm, password)
  dec = decipher.update(text, 'hex', 'utf8')
  dec += decipher.final('utf8')
  dec

file = fs.readFileSync './test.env.encrypted'

console.log decrypt file.toString('hex')

然后它产生了一个新的错误：

文件使用以下方式加密：

openssl aes-256-cbc -e -in test.env -out test.env.encrypted

带

test

作为密码

Answer 1

您对decipher.update的调用需要hex个编码字符串，但您传递的是utf-8字符串。

将readFileSync更改为使用hex编码阅读，或将update调用更改为期望utf-8输入。

使用node.js解密openssl aes-256-cbc？
