Spring Security之密码加密（五）

一、BCryptPasswordEncoder单独操作

1. 代码实现

package com.hzxy.utils;

import org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder;

public class BCryptPasswordEncoderUtils {
    private static BCryptPasswordEncoder bCryptPasswordEncoder=new BCryptPasswordEncoder();
    public static String encodePassword(String password){
        return bCryptPasswordEncoder.encode(password);
    }

    public static void main(String[] args) {
        String password="123";
        String pwd = encodePassword(password);
        
        System.out.print(pwd.length());
    }
}

2. 执行结果，每次加密结果都不一样

二、BCryptPasswordEncoder源码分析

public String encode(CharSequence rawPassword) {
		String salt;
		if (strength > 0) {
			if (random != null) {
				salt = BCrypt.gensalt(strength, random);
			}
			else {
				salt = BCrypt.gensalt(strength);
			}
		}
		else {
			salt = BCrypt.gensalt();
		}
		return BCrypt.hashpw(rawPassword.toString(), salt);
	}

三、使用Spring-Security.xml文件操作

 
<bean id="passwordEncoder" class="org.springframework.security.crypto.bcrypt.BCryptPasswordEncoder"/>
