java - 为 React Native 客户端获取与服务器端 Java 代码类似的密文

Question

我是 React Native 的新手。服务器端的人用 Java 编写了加密逻辑，如下所示

import java.io.UnsupportedEncodingException;
import java.security.MessageDigest;
import java.security.NoSuchAlgorithmException;
import java.util.Arrays;
import java.util.Base64;

import javax.crypto.Cipher;
import javax.crypto.spec.SecretKeySpec;

import org.springframework.beans.factory.annotation.Autowired;
import org.springframework.beans.factory.annotation.Value;
import org.springframework.stereotype.Service;

@Service
public class AES {

    @Autowired
    static AesProps props;

    private static String secretkey = "abcdefghijklmnopqhijklmnopq"; // Sample key

    private static SecretKeySpec secretKey;
    private static byte[] key;

    public static void setKey(String myKey) {
        MessageDigest sha = null;
        try {
            key = myKey.getBytes("UTF-8");
            sha = MessageDigest.getInstance("SHA-1");
            key = sha.digest(key);
            key = Arrays.copyOf(key, 16);
            secretKey = new SecretKeySpec(key, "AES");
        } catch (NoSuchAlgorithmException e) {
            e.printStackTrace();
        } catch (UnsupportedEncodingException e) {
            e.printStackTrace();
        }
    }

    public static String encrypt(String strToEncrypt) {
        try {
            setKey(secretkey);
            Cipher cipher = Cipher.getInstance("AES/ECB/PKCS5PADDING");
            cipher.init(Cipher.ENCRYPT_MODE, secretKey);
            return Base64.getEncoder().encodeToString(cipher.doFinal(strToEncrypt.getBytes("UTF-8")));
        } catch (Exception e) {
            System.out.println("Error while encrypting: " + e.toString());
        }
        return null;
    }

我正在尝试找到一种在 React Native 中加密的方法，这将为我提供与上述 Java 代码相同的密码。我经历过，react-native-aes-crypto但很多东西都不见了。喜欢怎么用PKCS5PADDING，怎么做对应SecretKeySpec。任何帮助将非常感激。
