安全测试 —— Jmeter 登录接口密码 - rsa加密

1、出于安全考虑，有的网站在登陆时为了防止用户在登录时账户密码泄漏，会使用各种加密，给登录的账户密码加密。

比如：明文保存，对称加密算法，MD5、SHA1等单向HASH算法，RSA算法，加密FBPDF2算法，bcrypt，scrypt等。

所以我们在做注册或者登录的性能测试时，需要借助脚本来解密成功调用接口。

2、登录密码使用RSA加密。注册或者登录的时候需要使用公钥给密码加密后，传给接口。

这时需要借助脚本代码将我们的密码用公钥加密（这里用的是Java的脚本）

3、详细的操作过程

①将ip地址和端口参数化

②给密码使用rsa算法加密，添加一个取样器：BeanShell取样器，粘贴脚本代码

脚本代码如下：

import org.apache.commons.codec.binary.Base64;
import java.io.ByteArrayOutputStream;
import java.security.Key;
import java.security.KeyFactory;
import java.security.KeyPair;
import java.security.KeyPairGenerator;
import java.security.PrivateKey;
import java.security.PublicKey;
import java.security.Signature;
import java.security.interfaces.RSAPrivateKey;
import java.security.interfaces.RSAPublicKey;
import java.security.spec.PKCS8EncodedKeySpec;
import java.security.spec.X509EncodedKeySpec;
import java.util.HashMap;
import java.util.Map;
import javax.crypto.Cipher;
String RSA_PUB_KEY="rsa公钥";
String KEY_ALGORITHM = "RSA";
String SIGNATURE_ALGORITHM = "MD5withRSA";
int MAX_ENCRYPT_BLOCK = 117;
int MAX_DECRYPT_BLOCK = 128;
 
public static byte[] decryptByPublicKey(byte[] encryptedData, String publicKey)
            throws Exception {
        byte[] keyBytes = Base64.decodeBase64(publicKey);
        X509EncodedKeySpec x509KeySpec = new X509EncodedKeySpec(keyBytes);
        KeyFactory keyFactory = KeyFactory.getInstance(KEY_ALGORITHM);
        Key publicK = keyFactory.generatePublic(x509KeySpec);
        Cipher cipher = Cipher.getInstance(keyFactory.getAlgorithm());
        cipher.init(Cipher.DECRYPT_MODE, publicK);
        int inputLen = encryptedData.length;
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        int offSet = 0;
        byte[] cache;
        int i = 0;
        // 对数据分段解密
        while (inputLen - offSet > 0) {
            if (inputLen - offSet > MAX_DECRYPT_BLOCK) {
                cache = cipher.doFinal(encryptedData, offSet, MAX_DECRYPT_BLOCK);
            } else {
                cache = cipher.doFinal(encryptedData, offSet, inputLen - offSet);
            }
            out.write(cache, 0, cache.length);
            i++;
            offSet = i * MAX_DECRYPT_BLOCK;
        }
        byte[] decryptedData = out.toByteArray();
        out.close();
        return decryptedData;
    }
    public static byte[] encryptByPublicKey(byte[] data, String publicKey)
            throws Exception {
        byte[] keyBytes = Base64.decodeBase64(publicKey);
        X509EncodedKeySpec x509KeySpec = new X509EncodedKeySpec(keyBytes);
        KeyFactory keyFactory = KeyFactory.getInstance(KEY_ALGORITHM);
        Key publicK = keyFactory.generatePublic(x509KeySpec);
        // 对数据加密
        Cipher cipher = Cipher.getInstance(keyFactory.getAlgorithm());
        cipher.init(Cipher.ENCRYPT_MODE, publicK);
        int inputLen = data.length;
        ByteArrayOutputStream out = new ByteArrayOutputStream();
        int offSet = 0;
        byte[] cache;
        int i = 0;
        // 对数据分段加密
        while (inputLen - offSet > 0) {
            if (inputLen - offSet > MAX_ENCRYPT_BLOCK) {
                cache = cipher.doFinal(data, offSet, MAX_ENCRYPT_BLOCK);
            } else {
                cache = cipher.doFinal(data, offSet, inputLen - offSet);
            }
            out.write(cache, 0, cache.length);
            i++;
            offSet = i * MAX_ENCRYPT_BLOCK;
        }
        byte[] encryptedData = out.toByteArray();
        out.close();
        return encryptedData;
    }
    String str = "登录密码";
String result ="";
try {
    result = Base64.encodeBase64String(encryptByPublicKey(str.getBytes(), RSA_PUB_KEY));
    System.out.println(result);
} catch (Exception e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}
print(result);
vars.put("sign",result);
return result;

注意：在脚本里面，在Java的脚本里面，最下面的string str =“登录密码”，你把引号里面的登录密码改成你帐号的密码就行

③在登录接口直接调用加密后的密码：{$sign}
