bcrypt
Go语言（Golang）密码加密存储（数据库中密码存储）
很多系统都是将密码进行一次 MD5 或 SHA1 Hash后存入数据库中。这样的密码抵挡不住字典攻击。所谓字典攻击，就是将常用密码进行Hash后做成一个字典，破解的时候，只需要查字典就能知道对应的明文密码。 为了抵御字典攻击，推荐的做法是使用 密码 + 盐（一串随机数） 再Hash的方式。每个密码对应一个不同的随机数。这个方法，实际上是将密码人为地拓展了N位，导致密码长度大增，使得攻击者无法构造这么大的一个字典。 Go语言提供了一种较为安全的加密方式，使用GoLang golang.org/x/crypto/bcrypt 模块，通过该模块可以快速实现密码的存储处理。 package main import ( "fmt" "golang.org/x/crypto/bcrypt" ) type User struct { Name string `json:"name"` Password string `json:"password"` } func main() { fmt.Println("====模拟注册====") u0 := User{} u0.Password = "pwd" //模拟注册是传递的密码 hash, err := bcrypt.GenerateFromPassword([]byte(u0.Password), bcrypt.DefaultCost) /
Spring Security 多种加密方案共存，老破旧系统整合利器！
关于密码加密的问题，松哥之前已经和大家聊过了，参考： Spring Boot 中密码加密的两种姿势！ 这篇文章中，松哥给大家介绍了两种密码加密方案，但是两种都是独立使用的！能不能在同一个项目中同时存在多种密码加密方案呢？答案是肯定的！ 今天松哥就来和大家聊一聊，如何在 Spring Security 中，让多种不同的密码加密方案并存。 本文是 Spring Security 系列第 31 篇，阅读前面文章有助于更好的理解本文： 挖一个大坑，Spring Security 开搞！ 松哥手把手带你入门 Spring Security，别再问密码怎么解密了 手把手教你定制 Spring Security 中的表单登录 Spring Security 做前后端分离，咱就别做页面跳转了！统统 JSON 交互 Spring Security 中的授权操作原来这么简单 Spring Security 如何将用户数据存入数据库？ Spring Security+Spring Data Jpa 强强联手，安全管理只有更简单！ Spring Boot + Spring Security 实现自动登录功能 Spring Boot 自动登录，安全风险要怎么控制？ 在微服务项目中，Spring Security 比 Shiro 强在哪？ SpringSecurity 自定义认证逻辑的两种方式(高级玩法)
Flask bcrypt.check_password_hash() always returns False, can't narrow in on my mistake
问题 While trying to write a login functionality in flask, I wanted to try 'bcrypt' flask extensio. When I use_bcrypt.check_password_hash()_ method to compare user form input password against that users saved password in the db, it always returns false. Here is the code I use to generate passwords: hashPwd = bcrypt.generate_password_hash('form.password.data') Here is the code I use to check the candidate password against the saved one: if form.validate_on_submit(): user = User.query.filter_by
why spring security gives empty password to password encoder?
问题 I am using spring security with BCrypt Password encoder for authentication. when i want to login, Spring security fetchs user data with JPA correctly but for checking raw password with encoded password it gives null string as encoded password to password encoder. spring security config : @Configuration public class SecurityConfig extends WebSecurityConfigurerAdapter { @Autowired @Qualifier("userDetailsServiceImpl") private UserDetailsService userDetailsService; @Bean public PasswordEncoder
Why does the Kivy app crash when using the paramiko module?
问题 I have an application using paramiko, the application itself is going well, but it crashes when you start it, I understand it's in the paramiko module. I have placed the white list next to main.py file and next to the black list file in the pythonforandroid/bootstraps/sdl2/build folder/ Part of my spec file: source.include_exts = py,png,jpg,kv,atlas requirements = kivy,kivymd,boto3,botocore,openssl,pyjnius,ecdsa,bcrypt,cryptography,paramiko, android osx.python_version = 3 osx.kivy_version = 1
how to compare a password text with the bcrypt hashes?
问题 I have a use case in my application that should prevent the user from choosing one of their last 3 passwords while resetting their password. I'm using Angular for the front end and Spring Boot for the back end . In my scenario, the user passwords are stored as bcrypt hash. How can I compare the password entered by the user with the last 3 stored bcrypt passwords? When I run the following code snipped example, BCryptPasswordEncoder b = new BCryptPasswordEncoder(); for(int i =0;i<10;i++) {
Decode the Bcrypt encoded password in spring security to Deactivate User account
问题 I am working on web application project in Spring Hibernate MVC. I am storing encoded password in the database using Bcrypt algorithm in Spring security. Now I want to get that encoded password to be decoded to deactivate Use account where in I am giving user email and password to verify before user deactivate the account. I have problem in getting decoded password. Can anyone help me to get out of it or any alternate solution for my requirement? 回答1: The problem is solved by using below code
NodeJS: bcrypt vs native crypto
问题 Can someone point out the differences between the two and example situations where use each? bcrypt looks great. 回答1: Use bcrypt where you want to do slow and computationally expensive hashing -- this will generally be for hashes where you really don't want an attacker to be able to reverse the hash, e.g. user passwords. Use native crypto for everything else. 回答2: In companion with the @mike-scott's answer, you should prefer bcrypt for password related stuff but still you can use crypto for a
Laravel中我们登录服务器通过 Tinker 手动创建后台管理用户
Laravel中我们可以登录到服务器通过 Tinker 手动创建后台用户 laravel中tinker命令的作用是用来调试laravel，可以打印变量或对象信息，显示函数代码，对数据库写入和查询数据。 输入help可以查看帮助信息。 tinker命令的启动方式为php artisan tinker，运行后出现的提示符为tinker的提示符 ，用于通过命令行与应用进行交互。 下面我们开始创建后台用户： php artisan tinker 这里有一个报错： ErrorException : exec() has been disabled for security reasons 解决：打开php.ini文件，搜索 disable_functions，找到如下类似内容： disable_functions=passthru,exec,system,chroot,scandir,chgrp,chown,shell_exec,proc_get_status,proc_open,popen,ini_alter,ini_restore,dl,openlog,syslog,readlink,symlink,popepassthru,stream_socket_server 找到exec并删除然后重启php服务。再次输入 php artisan tinker $user = new App
