Java 使用Jasypt解密

如何使用库解密加密的密码

尝试解密密码时控制台中显示错误：

Encrypted: JIOYXNa1+3+QefY2S7sas7LmhyOuDQcG8TTsQoTkqj0OtobCvwAFHXxoTr7z6HuP
org.jasypt.exceptions.EncryptionOperationNotPossibleException: Encryption raised an exception. A possible cause is you are using strong encryption algorithms and you have not installed the Java Cryptography Extension (JCE) Unlimited Strength Jurisdiction Policy Files in this Java Virtual Machine

你可以试试下面的例子。这将为您工作：请始终保持mpCryptoPassword值非常机密的位置，只有应用程序才能读取该值

public class EncryptionDecryptionUsingJASYPT {

    private static String mpCryptoPassword = "BornToFight";

    public static void main(String[] args) {
        String value = "Original Text: Eclipse";

        System.out.println("Original Value : "+value);
        StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();
        encryptor.setPassword(mpCryptoPassword);
        String encryptedPassword = encryptor.encrypt(value);
        System.out.println(encryptedPassword);

        StandardPBEStringEncryptor decryptor = new StandardPBEStringEncryptor();
        decryptor.setPassword(mpCryptoPassword);
        System.out.println(decryptor.decrypt(encryptedPassword));
    }
}

从命令生成的加密字符串未给出所需的结果，因为它无法加密像“！”这样的特殊字符。并给出错误“未找到事件”

KAD@ashutoshMINGW64~/桌面

$java-cp ~/.m2/repository/org/jasypt/jasypt/1.9.3/jasypt-1.9.3.jar org.jasypt.intf.cli.JasyptPBEStringEncryptionCLI input=“Test！email30#password”password=“some_salt” 算法=PBEWithMD5和DES

巴什：！email30#密码：未找到事件

下面是一个使用

org.jasypt.util.text.AES256TextEncryptor

这是一个实用类，用于轻松执行

文本的高强度加密

该类内部包含一个

标准bStringEncryptor

，配置方式如下：

• 算法：

  PBEWithHMACSHA512AndAES_256

• 关键获取迭代：

  1000

使用它所需的步骤包括：

创建一个实例（使用new）

设置密码（使用setPassword（字符串）或setPasswordCharArray（char[]）

执行所需的加密（字符串）或解密（字符串）操作

您可以在任何配置类或SpringBootApplication中使用

@EnableEncryptableProperties

。见示例：

import com.ulisesbocchio.jasyptspringboot.annotation.EnableEncryptableProperties;
import org.springframework.boot.SpringApplication;
import org.springframework.boot.autoconfigure.SpringBootApplication;
import org.springframework.boot.autoconfigure.domain.EntityScan;
import org.springframework.context.annotation.ComponentScan;
import org.springframework.data.jpa.repository.config.EnableJpaRepositories;
import org.springframework.transaction.annotation.EnableTransactionManagement;

@EnableEncryptableProperties
@SpringBootApplication
@ComponentScan(basePackages = {"com.company"})
@EntityScan(basePackages = {"com.company.persistence.entities"})
@EnableJpaRepositories(value = {"com.company.persistence.repository"})
@EnableTransactionManagement
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }

}

并且在任何属性/yml文件中：

<dependency>
        <groupId>com.github.ulisesbocchio</groupId>
        <artifactId>jasypt-spring-boot-starter</artifactId>
        <version>2.1.2</version>
    </dependency>

import org.jasypt.util.text.AES256TextEncryptor;
import java.security.NoSuchAlgorithmException;

public class JasyptPasswordEcryptor {
 public static void main(String[] args) throws NoSuchAlgorithmException {

    String password = "Test!email30#password";

    AES256TextEncryptor encryptor = new AES256TextEncryptor();
    encryptor.setPassword("some_salt");
    String myEncryptedText = encryptor.encrypt(password);
    System.out.println("Encrypted: "+myEncryptedText);

    String plainText = encryptor.decrypt(myEncryptedText);
    System.out.println("Decrypted: "+plainText);
 }
}

email:
    password:
        # DO-NOT-USE/REMOVE THIS
        plain: 'Test!email30#password'
        # use this encrypted one
        encrypted: ENC(fureWQHrflMinY+KBOcNeJyYmQv+7Ung/IclGz3iSBYKqTNdgslADg+TMcfFI/unaqZ/P3kDGPco2jZ4vIhrFw==)

@ᴜʀᴇsʜᴀᴛᴛᴀ 我们能解密加密的密码吗？是的，为什么不能。毕竟，它也是一个简单的字符串，就像任何其他字符串一样。如果它散列，则无法获取它。让我们看看CLI示例的问题是“！”是保留的shell字符。如果在该字符串周围使用单个QOUTE，则会阻止shell解释“！”并按预期工作。该错误消息来自您的shell，而不是Jasypt jar
