java - 线程 "main"org.jasypt.exceptions.EncryptionOperationNotPossibleException 中出现异常

Question

我真的很难解决这个错误:有人可以帮助我吗？

我使用了 jasypt 标准...请帮助。用过这个:http://www.jasypt.org/

我的演示代码？

import org.jasypt.encryption.pbe.StandardPBEStringEncryptor;

public class Demo {
    static StandardPBEStringEncryptor encryptor;
    public static String encryptString(String hash){
        encryptor = new StandardPBEStringEncryptor();
        encryptor.setPassword("ABXY"); 
        encryptor.setAlgorithm("PBEWithMD5AndTripleDES"); 
        return encryptor.encrypt(hash);
    }

    public static String decryptString(String hash){
        encryptor = new StandardPBEStringEncryptor();
        encryptor.setPassword("ABXY");
        return encryptor.decrypt(hash);
    }
    public static void main(String[] args) {
        Demo d = new Demo();
        String enc = d.encryptString("MyNewString@123");
        System.out.println("ENC : "+enc);

        String dec = d.decryptString(enc);
        System.out.println("DEC : "+dec);
    }
}

解密方法也应该设置算法。

public static String decryptString(String hash){
    encryptor = new StandardPBEStringEncryptor();
    encryptor.setAlgorithm("PBEWithMD5AndTripleDES"); 
    encryptor.setPassword("ABXY");
    return encryptor.decrypt(hash);
}
