cc_hashlib

• A C++ header-only hash algorithm library (including md5, sha1, sha256, sha224, sha384, sha512);

• Use this library like Python's hashlib;

• minimum required standard: C++11

• 这是一个header-only风格的C++哈希算法库 (包含md5, sha1, sha256, sha224, sha384, sha512等算法);

• 用法与Python的hashlib库类似

• 需要编译器支持C++11及以上的标准

• Modules can be compiled through the module unit file "hashlib.ixx"

• 可通过模块单元文件"hashlib.ixx"编译模块

• Support C++20 module (currently only supports MSVC compiler, and requires it enable to use import std; to import the standard library. if MSVC still can't use import std; under /std:c++latest, read"https://learn.microsoft.com/en-us/cpp/cpp/tutorial-import-stl-named-module?view=msvc-170"

• 支持C++20模块(目前只支持MSVC编译器, 并且要求其可以使用import std;导入标准库. 若MSVC在/std:c++latest下仍不能import std;, 可参考"https://learn.microsoft.com/zh-cn/cpp/cpp/tutorial-import-stl-named-module?view=msvc-170#import-the-standard-library-with-std")

import std;
import ccat.hashlib;

auto main() -> int {
    std::cout << ccat::hashlib::md5{}.update("Hello C++20 Modules").hexdigest(); // result: 113d5ad03d09b98cf4e22eb279bcdf8c
    return 0;
}

example/例子

• Use this library only including the header hashlib
• 仅需include头文件hashlib即可

#include "hashlib"

• Get md5 of a string by using ccat::hash::md5
• 使用ccat::hash::md5获取字符串的md5值

#include <iostream>
#include "hashlib"
auto main() ->int {
    ccat::hash::md5 m{"hello world"};
    std::cout << m.hexdigest() << '\n'; //result: 5eb63bbbe01eeed093cb22bb8f5acdc3
    return 0;
}

• And also you can use the method update or operator<<
• 你也可以使用update 或 operator<<

#include <iostream>
#include "hashlib"
auto main() ->int {
    ccat::hash::md5 m{};
    m.update("hello world"); //or m.update("hello"); m.update(" world");
    std::cout << m.hexdigest() << '\n'; //result: 5eb63bbbe01eeed093cb22bb8f5acdc3
    return 0;
}

#include <iostream>
#include "hashlib"
auto main() ->int {
    ccat::hash::md5 m{};
    m << "hello world"; //or `m << "hello" << " world";`
    std::cout << m.hexdigest() << '\n'; //result: 5eb63bbbe01eeed093cb22bb8f5acdc3
    return 0;
}

• Other hash algorithms are used in the same way as ccat::hash::md5
• More hash algorithms will be supported in the future
• 其它算法的用法与ccat::hash::md5相类似
• 后续将支持更多哈希算法
