Hello All,
I'm using FileSource to make a signature of a file. But I need to
read the file twice, since is a small file, thats OK, but what if was
a bigger file? Is there a way to use the filter to feed two (or maybe
possibly more) attachments? If there is such a way I can feed both the
SignerFilter and the FileSink simultaneously.
Here is my code (that is based on the examples located on the wiki):
FileSource privFile( PrivateKeyFile.c_str(), true, new
Base64Decoder );
RSASSA_PKCS1v15_SHA_Signer Signer( privFile );
string signature;
FileSource inFile( inFileName.c_str(), true,
new SignerFilter( GlobalRNG(), Signer,
new StringSink( signature )
)
);
FileSink fsink( "signed.txt" );
FileSource inFile2( inFileName.c_str(), true, new Redirector
(fsink ) );
string endoffile = "\n\x1b\n"; //newline,ESC,newline. Just to
separate the signature from the file
fsink.Put( (const byte*)endoffile.c_str(), endoffile.size(),
true );
StringSource inSign( signature.c_str(), true, new Redirector
(fsink) );
Thanks in advance,
