使用bcrypt哈希密码进行身份验证
在我的C ++应用程序中，用户必须登录才能使用该应用程序. 用户登录数据取自phpBB 3.1数据库，该数据库用于密码哈希bcrypt.但是，我没有找到适合C ++的任何示例.
In my C++ application, user must login in order to use the application. The user login data are taken from phpBB 3.1 database, which uses for password hashing bcrypt. However, I didn't found any suitable example for C++.
所以我的问题是:
如何在C ++中使用bcrypt哈希密码对用户进行身份验证?我知道如何使用C ++从外部数据库进行身份验证，我只需要bcrypt的帮助.
How I can auth user with bcrypt hashed password in C++? I know how to do authentication from external database in C++, I just need help with the bcrypt.
谢谢！
BCrypt确实不如可能常见，但是有一个 Openwall的crypt_blowfish .
BCrypt is really not as common as it could be, but there is a * question on What's the recommended Bcrypt C implementation? that will point you to Openwall's crypt_blowfish.
考虑到可靠的C实现，您只需包装一下C ++代码就可以了！
Given a solid C implementation, you need only a wrapper for your C++ code to be good to go!
我还要指出，最有用的Google结果实际上就是这个问题.特别是，Crypto ++库在其计划的功能列表中仍然具有BCrypt.
I would also note that the single most useful Google result is, in fact, this question. In particular, the Crypto++ library still has BCrypt on their planned features list.
使用时，别忘了将工作系数提高到12或14以上！
Don't forget to increase the work factor above 12 or 14 when you use it!
一旦有了可行的实现，如果您想提供合理的开源许可证，我很乐意将其包含在
Once you have a working implementation, if you'd like to give a reasonable open source license, I'd be happy to include it in my Github repository to provide an alternative to PBKDF2 examples!
