Nodejs中如何使用openssl aes-128-cbc加密？ nodejs的crypto库只认16位密钥……

openssl enc -d -aes-128-cbc -in ./1qaz  -K bc1f89d3421a6f097262c348890a9acc  -out decrypted.jpg -iv bc1f89d3421a6f097262c348890a9acc

我用 nodejs 这么写，一直报错 Invalid IV length 求教。。。。

const crypto = require("crypto");
const key = "bc1f89d3421a6f097262c348890a9acc";
const iv = key;
const cipher = crypto.createCipheriv('aes-128-cbc', key, iv);
const encryptedBytes = fs.readFileSync(’./1qaz’);
cipher.update(encryptedBytes);
const data = cipher.final(‘hex’);
console.log(‘data’, data);
