我尝试使用加密来加密文件。这里是我的代码:Nodejs 6.10.2 crypto AES密钥长度无效
const crypto = require('crypto');
const fs = require('fs');
const input = fs.createReadStream('test.jpg');
const output = fs.createWriteStream('test.enc');
const sharedSecret = crypto.randomBytes(256);
const initializationVector = crypto.randomBytes(16);
const cipher = crypto.createCipheriv('aes-256-cbc', sharedSecret, initializationVector);
input.pipe(cipher).pipe(output);
我得到了错误:
crypto.js:191
this._handle.initiv(cipher, toBuf(key), toBuf(iv));
^
Error: Invalid key length

我虽然sharedSecret长度应该是相同的AES-长度,但事实并非如此。我应该使用多长时间?谢谢:)
OMG,我看着办吧,长传球randomBytes要分8,因为它是字节而不是位。 –
