来自CryptoJS的Java解密

我正在尝试解密Java大小的一些信息，这些信息以前是用CryptoJS（angualrjs）加密的。 以下是一些代码片段：

Angularjs加密

CryptoJS.AES.encrypt(message, "my secret key").toString();

在Java中解密

package com.mypackage;

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;

public class AES {
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 decrypt(String strToDecrypt, String secret) {
    try{
        setKey(secret);
        
        Cipher cipher = Cipher.getInstance("AES/CBC/PKCS5Padding");
        cipher.init(Cipher.DECRYPT_MODE, AES.secretKey);
        return new String(cipher.doFinal(Base64.getDecoder().decode(strToDecrypt)));
    } catch (Exception e) {
        System.out.println("Error while decrypting: " + e.toString());
    }
    return null;
}
}

Key: 1234567890123456 (Both Angular and Java side)

Clear data: this is my text

Chipered data in CryptoJS: U2FsdGVkX18C7J5wy5R5FRjfP5Xghpry3FtuTj5xq+o=

What Java backend receives: U2FsdGVkX18C7J5wy5R5FRjfP5Xghpry3FtuTj5xq+o=

调用java解密方法

@PostMapping("/decryption")
public ResponseEntity<DecryptResponseBean> decryption(@RequestBody DecryptRequestBean data){
    String dataToDecrypt = data.getData();
    String decrypted = AES.decrypt(dataToDecrypt, "my secret key");
    
    DecryptResponseBean responseBean = new DecryptResponseBean(decrypted);
    return ResponseEntity.ok(responseBean);
}

        return new String(cipher.doFinal(Base64.getDecoder().decode(strToDecrypt)));
    } catch (Exception e) {

    }
    return null;

在Stackoverflow上搜索一下，您就可以找到与此相同的解决方案。重要的代码不是我自己写的，而是作者@Codo的答案，所以所有的功劳都归于他

Crypto.JS从密码短语（“密钥”）中导出密钥和初始化向量（iv），因此方法

GenerateKeyAndIV

负责获取密钥和iv

以下代码没有适当的异常处理，仅用于教育目的。

结果:

Java decryption from CryptoJS
decrypted text: this is my text
expected data:  this is my text

代码：

您是否可以包含实际的堆栈跟踪，以便用户可以在提供的代码中看到异常发生的位置和时间！。。。提供一整套样本数据（明文、密钥和密文=加密文本）可能会有所帮助。请编辑您的帖子并添加数据，谢谢。添加了请求的详细信息，谢谢。这解决了问题，似乎我可以正确地从前端到后端加密/解密数据。谢谢！
