How do you convert this DES encryption code from Java code to JavaScript?
问题
const crypto = require('crypto');function getSignature(skey, iv, data) {const IV = Buffer.from(iv, 'utf-8');const desKey = Buffer.from(skey, 'utf-8');const cipher = crypto.createCipheriv('des-cbc', desKey, IV);let encrypted = cipher.update(data, 'utf-8', 'base64');encrypted += cipher.final('base64');return encrypted;}

How can I convert this Java code to JavaScript?
public static String getSignature(String skey, String iv, String data) throws Exception {IvParameterSpec Ⅳ = new IvParameterSpec(iv.getBytes("utf-8"));DESKeySpec desKey = new DESKeySpec(skey.getBytes("utf-8"));SecretKeyFactory keyFactory = SecretKeyFactory.getInstance("DES");SecretKey key = keyFactory.generateSecret(desKey);Cipher cipher = Cipher.getInstance("DES/CBC/PKCS5Padding");cipher.init(Cipher.ENCRYPT_MODE, key, Ⅳ);byte[] databyte = cipher.doFinal(data.getBytes("utf-8"));return new String(Base64.getEncoder().encode(databyte));}
I tried it myself, and I got:
function getSignature(skey,iv,data,) {const IV = Buffer.from(ivString, 'utf-8');const desKey = Buffer.from(skey, 'utf-8');const cipher = crypto.createCipheriv('des-cbc', desKey, IV);let encrypted = cipher.update(data, 'utf-8', 'base64');encrypted += cipher.final('base64');return encrypted;}
But I got an ERR_CRYPTO_INVALID_KEYLEN error, because my key is not 8 in length. I'm guessing that my JavaScript code is missing this part of the Java code, but I don't know how to translate this part into JavaScript...:
SecretKeyFactory keyFactory = SecretKeyFactory.getInstance("DES");SecretKey key = keyFactory.generateSecret(desKey);

以下是代码的中文翻译部分：
const crypto = require('crypto');function getSignature(skey, iv, data) {const IV = Buffer.from(iv, 'utf-8');const desKey = Buffer.from(skey, 'utf-8');const cipher = crypto.createCipheriv('des', desKey.slice(0, 8), IV);let encrypted = cipher.update(data, 'utf-8', 'base64');encrypted += cipher.final('base64');return encrypted;}
英文:
const crypto = require('crypto');function getSignature(skey, iv, data) {const IV = Buffer.from(iv, 'utf-8');const desKey = Buffer.from(skey, 'utf-8');const cipher = crypto.createCipheriv('des', desKey.slice(0, 8), IV);let encrypted = cipher.update(data, 'utf-8', 'base64');encrypted += cipher.final('base64');return encrypted;}
