Question

我正在尝试编写Javascript以匹配此Java代码的输出：

爪哇：

import java.util.Base64;

public class Enc2 {
    public static void main (String[] arg) {
        System.out.println(encryptSomeNumber("1234567812345678"));
    }

    public static String encryptSomeNumber(final String SomeNumber){
        String encryptedSomeNum = "";
        String ALGO = "AES";

        try {
            String myKey = "DLDiGPqGysAow3II";
            byte[] keyBytes = myKey.getBytes("UTF-8");

            java.security.Key encryptkey = new javax.crypto.spec.SecretKeySpec(keyBytes, ALGO);
            javax.crypto.Cipher c;
            c = javax.crypto.Cipher.getInstance(ALGO);
            c.init(javax.crypto.Cipher.ENCRYPT_MODE, encryptkey);
            byte[] encVal = c.doFinal(SomeNumber.getBytes());

            byte[] encodedBytes = Base64.getEncoder().encode(encVal);
            String s = new String(encodedBytes);

            encryptedSomeNum = s;
        } catch (Exception e) {
            System.out.println("error when encrypting number");
            return encryptedSomeNum;
        }
        return encryptedSomeNum;
    }
}

输出：Wrs66TuAIxYe + M4fqyyxtkyMFkWGwx9i45 + oQfEA4Xs =

我到目前为止的Javascript（nodeJS v8.7.0）：

let crypto = require('crypto');

let algorithm = 'aes-128-ecb';
let password = 'DLDiGPqGysAow3II';

function encrypt(buffer){
    let cipher = crypto.createCipher(algorithm, password)
    let crypted = Buffer.concat([cipher.update(buffer), cipher.final()]);
    return crypted;
}

let cyphertext = encrypt(new Buffer("1234567812345678", "utf8"))
console.log(cyphertext.toString('base64'));

输出：m1jnKjBbKu + m / zsf9DBTMo3NL4E035l0EailFjt / qjo =

谁能看到我在这里缺少的东西？ PKCS填充的东西？

Answer 1

不，填充是一样的。问题是有两种createCipher方法。一个是使用密码和密钥派生函数而不是密码 - 这是您现在使用的密码。另一个使用密钥和IV。当然，欧洲央行不使用IV，因此您可能必须提供未使用的IV值。
