Hi,
I am testing the samples in
http://itextpdf.sourceforge.net/howtosign.html#signextitextsharp2 to see how
it works the signature process in ItextSharp, but I found that those samples
does not work, in my case every time I try to sign a PDF hapens the
following:
Stream s = sap.RangeStream;
int read = 0;
byte[] buff = new byte[8192];
while ((read = s.Read(buff, 0, 8192)) > 0) {
sha.TransformBlock(buff, 0, read, buff, 0);
}
the call to sap.RangeStream returns always an empty Stream, provoquing the
attempt to sign an empty Hash.
I copied the samples exactly as they are on the web, but the same thing
hapens with the functions SignHashed() and SignDetached().
Are the samples wrong, am I missing something?
thanks.
