如何將此 Java 程式碼轉換為 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)); }
我自己試了一下,結果是:
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; }
但我收到了 ERR_CRYPTO_INVALID_KEYLEN
錯誤,因為我的金鑰長度不是 8。我猜我的 JavaScript 程式碼缺少這部分 Java 程式碼,但我不知道如何將這部分翻譯成 JavaScript...:
SecretKeyFactory keyFactory = SecretKeyFactory.getInstance("DES"); SecretKey key = keyFactory.generateSecret(desKey);

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; }
