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 availableSecretKey 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);
