加密解密使用jasypt

Question

如何使用加密密码解密jasypt.

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();
        }
    }
}

使用jasypt解密密码时,控制台中会显示错误.

您可以尝试以下示例.这对你有用:请始终保持mpCryptoPassword值非常秘密的位置,只有应用程序应该能够读取.

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));
    }
}
