使用Jasypt解密

Question

如何使用Jasypt库解密加密密码？

package com.uk.mysqlmaven.jsf.test;

import org.jasypt.util.password.StrongPasswordEncryptor;
import org.jasypt.util.text.StrongTextEncryptor;


public class PasswordEncryptionDecryptionUsingJASYPT {
    public static void main(String[] args) {
        try {
            String password = "password";
            StrongPasswordEncryptor encryptor = new StrongPasswordEncryptor();
            String encryptedPassword = encryptor.encryptPassword(password);
            if (encryptor.checkPassword(password, encryptedPassword)) {
                //correct
                System.out.println("Encrypted: "+ encryptedPassword);
            } else {
                //bad again
                System.out.println("Error: ");
            }
            StrongTextEncryptor textEncryptor = new StrongTextEncryptor();
            textEncryptor.setPassword(encryptedPassword);
            String decryptedPassword = textEncryptor.decrypt(encryptedPassword);
            System.out.println("Decrypted: "+ decryptedPassword);
            
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

当试图解密密码时，控制台中会显示错误：

Answer 1

您可以尝试下面的示例。这将为您工作:请始终保持mpCryptoPassword值非常秘密的位置，只有应用程序应该能够阅读。

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));
    }
}

Answer 2

从命令生成的加密字符串不能给出所需的结果，因为它不能加密特殊字符，例如"!".and给出的错误“事件未找到”。

KAD@ashutosh MINGW64 ~/桌面 $ java ~/.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”algorithm=PBEWithMD5AndDES“ bash：!email30#password:找不到事件

下面是一个使用org.jasypt.util.text.AES256TextEncryptor的示例，这是一个易于执行high-strength encryption of texts的实用类。

这个类内部保存一个以这种方式配置的StandardPBEStringEncryptor：

• 算法：PBEWithHMACSHA512AndAES_256.
• 密钥获取迭代：1000。

使用它所需的步骤是：

1. 创建一个实例(使用new)。
2. 设置密码(使用setPassword(字符串)或setPasswordCharArray(char[]))。
3. 执行所需的加密(字符串)或解密(字符串)操作。

pom.xml:

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

您可以使用JasypUpdate2.1.2(带引导2.1.1)或jasypt-1.9.3.jar。

Java代码：

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);
 }
}

输出：

加密: fureWQHrflMinY+KBOcNeJyYmQv+7Ung/IclGz3iSBYKqTNdgslADg+TMcfFI/unaqZ/P3kDGPco2jZ4vIhrFw== 解密:测试！email30#password

Spring启动集成：

您可以在任意配置类或@EnableEncryptableProperties中使用@SpringBootApplication。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);
    }

}

和任何属性/yml文件：

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

jasypt:
    encryptor:
        password: some_salt
