[Code 02] std::ofstream ofs(enc_file, std::ios_base::trunc); ofs.write(reinterpret_cast<const char *>(iv.data()), iv.size() * sizeof(byte ) / sizeof(char)); FileSource(src_file.c_str(), true, new AuthenticatedEncryptionFilter(e, new FileSink(ofs)));
Like above. The content in binary file "enc_file" is not "IV + encrypted". I doubt FileSink Constructor "FileSink (std::ostream &out)" will modify std::ostream rather than continuing writing stream. 在 2018年6月26日星期二 UTC+8下午3:40:14，Jeffrey Walton写道： > > > > On Tuesday, June 26, 2018 at 2:13:25 AM UTC-4, Martin wrote: >> >> ... >> >> Question: >> >> FileSource(<src>, true, new AuthenticatedEncryptionFilter(e, new >> FileSink(<ofs>))); >> >> FileSink (std::ostream &out) >> >> Will CryptoPP::FileSink overwriter previous byte stream of <ofs>? >> > > The FileSInk opens the stream using the default ostream flags.
