jmeter-AES加密

news 来源：原创 2025/5/25 7:38:30

AES(全称：Advanced Encryption Standard)对称加密算法，也就是加密和解密用到的密钥是相同的，这种加密方式加密速度非常快，

适合经常发送数据的场合，如：数据加密存储、网络通信加密等。

在进行接口测试或接口压测时，有些比较核心的接口有可能会用AES方式对接口的入参或响应内容进行加密/解密。

Jmeter 对AES加密/解密，当前可以通过beanshell 的方式处理。

代码如下：

import javax.crypto.Cipher;
import javax.crypto.KeyGenerator;
import javax.crypto.SecretKey;
import javax.crypto.spec.SecretKeySpec;
import java.security.SecureRandom;
import java.util.Base64;
 
public class AESUtil {
 
    // AES密钥算法
    private static final String KEY_ALGORITHM = "AES";
 
    // 加密/解密算法/工作模式/填充方式
    private static final String CIPHER_ALGORITHM = "AES/ECB/PKCS5Padding";
 
    // 生成密钥
    public static String generateAESKey() throws Exception {
        KeyGenerator keyGenerator = KeyGenerator.getInstance(KEY_ALGORITHM);
        keyGenerator.init(128, new SecureRandom()); // 192 and 256 bits may not be available
        SecretKey secretKey = keyGenerator.generateKey();
        return Base64.getEncoder().encodeToString(secretKey.getEncoded());
    }
 
    // AES加密
    public static String encryptAES(String data, String key) throws Exception {
        Cipher cipher = Cipher.getInstance(CIPHER_ALGORITHM);
        SecretKeySpec secretKeySpec = new SecretKeySpec(Base64.getDecoder().decode(key), KEY_ALGORITHM);
        cipher.init(Cipher.ENCRYPT_MODE, secretKeySpec);
        byte[] encrypted = cipher.doFinal(data.getBytes());
        return Base64.getEncoder().encodeToString(encrypted);
    }

    // 解密
    public static String decryptAES(String data, String key) throws Exception {
        Cipher cipher = Cipher.getInstance(CIPHER_ALGORITHM);
        SecretKeySpec secretKeySpec = new SecretKeySpec(Base64.getDecoder().decode(key), KEY_ALGORITHM);
        cipher.init(Cipher.DECRYPT_MODE, secretKeySpec);
        byte[] decrypted = cipher.doFinal(Base64.getDecoder().decode(data));
        return new String(decrypted);
    }
 
    public static void main(String[] args) throws Exception {
        String key = generateAESKey();
        String originalText = "Hello World!";
        String encryptedText = encryptAES(originalText, key);
        System.out.println("Encrypted Text: " + encryptedText);
        // 解密操作
        // String decryptedText = decryptAES(encryptedText, key);
        // System.out.println("Decrypted Text: " + decryptedText);
    }
}

AESUtil aes_obj = new AESUtil();
String key = aes_obj.generateAESKey();
String originalText = "Hello World!";
String value = aes_obj.encryptAES(originalText,key);
log.info("密钥key: "+key);
log.info("AES加密结果："+value);
//解密
String decryptedText = aes_obj.decryptAES(value, key);
log.info("AES解密结果："+decryptedText);
// 将加密结果设置为jmeter参数
vars.put("AES_value",value);
