Ok, so I have this code:
CryptoPP::FileSource fileContentSrc(filePath.c_str(), false, new CryptoPP::
StringSink(fileContent));
while(!fileContentSrc.SourceExhausted()) {
fileContentSrc.Pump(16);
//So what now? Have no idea what to do. :(
}
I really have no idea what to do. The examples on
https://www.cryptopp.com/wiki/Pumping_Data
<ttps://www.cryptopp.com/wiki/Pumping_Data> seems much complex to me.
