Fwd: [cryptopp-users] unicode file name

[fa]

 

Hi One Sini


Thanks for your reply, but my problem is not related to file permission or 
insufficient privileges. No errors occurred when I do this operation with 
English characters, but errors occur when I use UTF-8 characters. I think 
the Cryptopp library has a problem with UTF-8 characters.

Hi Jeffrey Walton


Sorry I answered late.


std::filesystem::path _path { 
std::filesystem::u8path(filePath.toStdString()) };

std::string _path_string { _path.u8string() };

std::ifstream m_file(_path_string, std::ios::in);

FileSource f(m_file, true, new HashFilter(hash, new HexEncoder(new 
StringSink(digest; 



ERROR:


terminate called after throwing an instance of 
'CryptoPP::FileStore::ReadErr'

what(): FileStore: error reading file

Thanks to Jeffrey Walton and coshvji cujmlqef

I tried both of your methods but they both print the following errors:

terminate called after throwing an instance of 
'CryptoPP::FileStore::ReadErr'
what():  FileStore: error reading file

I tried two methods: 


1.


void CryptoHashes::makeFileHash(const QString )

{

FileSource f(filePath.toStdString().c_str(), true, new HashFilter(hash, new 
HexEncoder(new StringSink(digest;

}



2.


void CryptoHashes::makeFileHash(const QString )

{

std::filesystem::path _path { 
std::filesystem::u8path(filePath.toStdString()) };

std::ifstream m_file(_path, std::ios::in);


FileSource f(m_file, true, new HashFilter(hash, new HexEncoder(new 
StringSink(digest;

}



the only exception is that when I tried method 2, it always calculated hash 
of NULL, no matter which file I selected.
