密码加密Md5Hash和SimpleHash

加密算法 盐 迭代次数 Hex/Base64

package com.mozq.shiro.shiro01.test;

import org.apache.shiro.crypto.hash.Md5Hash;
import org.apache.shiro.crypto.hash.SimpleHash;

public class CryptoTest_01 {
    public static void main(String[] args) {
        String password = "changhe";

        int hashIterations = 5;
        //哈希

        System.out.println(simpleHash.toString());//96ff601332575cb7c3be7304aaad57b1
        /*
        Md5Hash继承SimpleHash。能使用Md5Hash的地方就能够使用SimpleHash。只用看2个类的构造器就可以明白它们的关系。
        
        Hex/Base64
        再者就是SimpleHash的 toString() toHex() toBase64() 3个方法的关系。
        它们与 HashedCredentialsMatcher 的 storedCredentialsHexEncoded 字段是对应的。

密码解密HashedCredentialsMatcher和SimpleAuthenticationInfo

HashedCredentialsMatcher 存储 加密算法 迭代次数 Hex/Base64

SimpleAuthenticationInfo 存储 盐 加密后字符串

UsernamePasswordToken 存储登录时用户名和密码。

hashedCredentialsMatcher.doCredentialsMatch(token, info) 方法完成认证。

加密后字符串 = 原密码 + 加密算法 + 盐 + 迭代次数 + Hex/Base64

        Exception in thread "main" java.lang.IllegalArgumentException: Odd number of characters.
        原因：new SimpleAuthenticationInfo(username, hashPassword, "MozqRealm") 传入的是原始密码，匹配器中匹配时出错。

        false
