如何使用jasypt解密加密的密码.

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();

}
