使用CryptoPP生成随机散列sha1 [英] Using CryptoPP to generate random hashes sha1
本文介绍了使用CryptoPP生成随机散列sha1的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!
问题描述
我需要使用CryptoPP生成一个随机散列,使用SHA1。在分钟我有:
I need to generate a random hash using CryptoPP, using SHA1. At the minute I have:
#include <cryptopp/sha.h>
#include <cryptopp/filters.h>
#include <cryptopp/hex.h>
...
CryptoPP::SHA1 sha1;
string source = "Hello"; //This will be randomly generated somehow
string hash = "";
StringSource(source, true, new HashFilter(sha1, new HexEncoder(new StringSink(hash))));
当我来编译时,我得到以下错误报告:
When I come to compile, I get the following error reported:
error: expected type-specifier before 'HashFilter'
error: expected ')' before 'HashFilter'
error: 'StringSource' was not declared in this scope
任何人都可以帮助我得到这个工作?有一个更简单的方法来执行这个使用这个库?我是使用Crypto ++的新手,所以所有的帮助将非常感激。
Can anyone help me to get this working? Is there a much simpler way of performing this using this library? I am new to using Crypto++ so all help will be much appreciated.
谢谢。
推荐答案
只要正确而仔细地指定命名空间:
Just specify your namespaces correctly and carefully:
#include <cryptopp/sha.h>
#include <cryptopp/filters.h>
#include <cryptopp/hex.h>
#include <string>
int main()
{
CryptoPP::SHA1 sha1;
std::string source = "Hello"; //This will be randomly generated somehow
std::string hash = "";
CryptoPP::StringSource(source, true, new CryptoPP::HashFilter(sha1, new CryptoPP::HexEncoder(new CryptoPP::StringSink(hash))));
}
