JMeter密码加密

要实现JMeter密码加密，可以使用以下代码示例：

1. 导入所需的包：

import org.apache.jmeter.util.JsseSSLManager;
import org.apache.jmeter.util.keystore.JmeterKeyStore;
import org.bouncycastle.crypto.CryptoException;
import org.bouncycastle.crypto.engines.AESFastEngine;
import org.bouncycastle.crypto.modes.GCMBlockCipher;
import org.bouncycastle.crypto.params.AEADParameters;
import org.bouncycastle.crypto.params.KeyParameter;
import org.bouncycastle.crypto.params.ParametersWithIV;
import org.bouncycastle.crypto.util.PaddedBufferedBlockCipher;
import org.bouncycastle.util.encoders.Base64;
import org.bouncycastle.util.encoders.Hex;
import java.security.Key;
import java.security.SecureRandom;
import java.util.Arrays;

2. 创建一个加密方法：

public static String encryptPassword(String password) throws CryptoException {
    try {
        // 生成随机密钥
        KeyParameter keyParameter = generateKey();
        // 生成随机IV
        byte[] iv = generateIV();
        
        // 创建加密器
        PaddedBufferedBlockCipher cipher = new PaddedBufferedBlockCipher(new GCMBlockCipher(new AESFastEngine()));
        // 初始化加密器
        cipher.init(true, new ParametersWithIV(keyParameter, iv));
        
        // 加密密码
        byte[] input = password.getBytes("UTF-8");
        byte[] output = new byte[cipher.getOutputSize(input.length)];
        int len = cipher.processBytes(input, 0, input.length, output, 0);
        cipher.doFinal(output, len);
        
        // 将密文和IV进行Base64编码
        byte[] encryptedBytes = Arrays.copyOf(output, len);
        byte[] encodedBytes = Base64.encode(encryptedBytes);
        byte[] encodedIV = Base64.encode(iv);
        
        // 将密文和IV拼接成最终的加密字符串
        StringBuilder sb = new StringBuilder();
        sb.append(new String(encodedBytes)).append(":").append(new String(encodedIV));
        
        return sb.toString();
    } catch (Exception e) {
        throw new CryptoException("Failed to encrypt password", e);
    }
}

3. 创建一个解密方法：

public static String decryptPassword(String encryptedPassword) throws CryptoException {
    try {
        // 分割密文和IV
        String[] parts = encryptedPassword.split(":");
        byte[] encryptedBytes = Base64.decode(parts[0].getBytes());
        byte[] iv = Base64.decode(parts[1].getBytes());
        
        // 创建解密器
        PaddedBufferedBlockCipher cipher = new PaddedBufferedBlockCipher(new GCMBlockCipher(new AESFastEngine()));
        // 初始化解密器
        cipher.init(false, new ParametersWithIV(generateKey(), iv));
        
        // 解密密码
        byte[] output = new byte[cipher.getOutputSize(encryptedBytes.length)];
        int len = cipher.processBytes(encryptedBytes, 0, encryptedBytes.length, output, 0);
        cipher.doFinal(output, len);
        
        // 返回明文密码
        return new String(output, "UTF-8");
    } catch (Exception e) {
        throw new CryptoException("Failed to decrypt password", e);
    }
}

4. 创建一个生成随机密钥的方法：

private static KeyParameter generateKey() throws CryptoException {
    try {
        // 从JMeter的密钥库中读取密钥
        JmeterKeyStore jks = JsseSSLManager.getKeyStore();
        Key key = jks.getKey("jmeter", "password".toCharArray()); // 替换为正确的密钥别名和密码
        
        // 对密钥进行处理
        byte[] encodedKey = key.getEncoded();
        byte[] keyBytes = Hex.encode(encodedKey);
        
        // 使用密钥字节数组生成KeyParameter对象
        return new KeyParameter(keyBytes);
    } catch (Exception e) {
        throw new CryptoException("Failed to generate key", e);
    }
}

5. 创建一个生成随机IV的方法：

private static byte[] generateIV() throws CryptoException {
    try {
        // 创建一个随机的IV字节数组
        byte[] iv = new byte[16];
        SecureRandom random = new SecureRandom();
        random.nextBytes(iv);
        
        return iv;
    } catch (Exception e) {
        throw new CryptoException("Failed to generate IV", e);
    }
}
