Java Springboot自定义Jasypt解密

1、pom

<dependency>
            <groupId>com.github.ulisesbocchio</groupId>
            <artifactId>jasypt-spring-boot</artifactId>
            <version>3.0.4</version>
        </dependency>

2、程序主函数添加注解

@EnableEncryptableProperties

3、加密解密封装类

import org.jasypt.encryption.pbe.StandardPBEStringEncryptor;
import org.jasypt.encryption.pbe.config.EnvironmentStringPBEConfig;

public class JasyptUtils {

    private final static String JASYPT_PASSWORD = "your_password";
    private final static String JASYPT_ALGORITHM = "PBEWithMD5AndDES";
//    private final static String JASYPT_ALGORITHM = "PBEWITHHMACSHA512ANDAES_256";

    /**
     * 加密
     *
     * @param plaintext 明文
     * @return
     */
    public static String encrypt(String plaintext) {
        StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();
        EnvironmentStringPBEConfig config = new EnvironmentStringPBEConfig();
        // 指定算法
        config.setAlgorithm(JASYPT_ALGORITHM);
        // 指定秘钥，和yml配置文件中保持一致
        config.setPassword(JASYPT_PASSWORD);
        encryptor.setConfig(config);
        // 生成加密数据
        return encryptor.encrypt(plaintext);
    }

    /**
     * 解密
     *
     * @param data 加密后数据
     * @return
     */
    public static String decrypt(String data) {
        StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();
        EnvironmentStringPBEConfig config = new EnvironmentStringPBEConfig();
        config.setAlgorithm(JASYPT_ALGORITHM);
        config.setPassword(JASYPT_PASSWORD);
        encryptor.setConfig(config);
        // 解密数据
        return encryptor.decrypt(data);
    }
}

4、自定义解析类

import cn.nosya.study.util.JasyptUtils;
import org.jasypt.encryption.StringEncryptor;
import org.springframework.stereotype.Component;

@Component
public class CustomDecryptor implements StringEncryptor {

    @Override
    public String encrypt(String s) {
        return JasyptUtils.encrypt(s);
    }

    @Override
    public String decrypt(String encrypted) {
        return JasyptUtils.decrypt(encrypted);
    }
}

5、配置文件指定上面的解析类

jasypt.encryptor.bean=customDecryptor

 6、bat文件制作加密解密工具

加密：
java -cp jasypt-1.9.3.jar org.jasypt.intf.cli.JasyptPBEStringEncryptionCLI password=0123456789abcdeffedcba9876543210 algorithm=PBEWithMD5AndDES input=123456!

解密：
java -cp jasypt-1.9.2.jar org.jasypt.intf.cli.JasyptPBEStringDecryptionCLI input="加密后的密文" password=jasypt配置密码 algorithm=PBEWithMD5AndDES
