-----------------------------
public byte[] sign(InputStream @is)
{
InputStream ipstream = @is;
byte[] pdf = null;
pdf = docSigDict["doc"];
return pdf;
}
whats looks wrong in sign method i am just calculating signature bytes from
response and returning it from sign method. Is there any way to insert the
signature at proper byte range offset so that my signature gets valid. thanks.
