Hello All, i have a weird problem. I generated XML digital signature and dumped it into a xmldsig.txt file. when i am trying read this xmlfile in chuncks like fread(tempbuffer, 1, 900, xmlfile);
where tempbuffer is a temporary character buffer xmlfile is a pointer to the xmlfile. then later i did fseek(xmlfile, 900, SEEK_SET); the file pointer is not seeking to the exact location for example.. for the first time the following is read <?xml version="1.0" encoding="UTF-8"?> <!-- XML Security Library example: Simple signature template file for sign1 example. --> <Envelope xmlns="urn:envelope"> <Data>AAABV4AJACYABwAIAAAAAQAIABZTYW1wbGUgQXBwbGljYXRpb24=</Data> <Signature xmlns="http://www.w3.org/2000/09/xmldsig#";> <SignedInfo> <CanonicalizationMethod Algorithm="http://www.w3.org/TR/2001/REC-xml-c14n-20010315"/> <SignatureMethod Algorithm="http://www.w3.org/2000/09/xmldsig#rsa-sha1"/> <Reference URI=""> <Transforms> <Transform Algorithm="http://www.w3.org/2000/09/xmldsig#enveloped-signature"/> </Transforms> <DigestMethod Algorithm="http://www.w3.org/2000/09/xmldsig#sha1"/> <DigestValue>Jmo893F0/j7Uw8T7katq89rDYVk=</DigestValue> </Reference> </SignedInfo> <SignatureValue>HdVAe/z9KXCCFpIs9e77X4DUdKmPyq21oa4JDuc4fn3j8KMZnQoTWEQ6kJsWyzp1 /aFwNR IN THE second time the following is read EQ6kJsWyzp1 /aFwNRSpft3Rd4KDZyczGsR6PCv+Pu8E0c+Cao5hb7NTduKbkqSxztViotSoZ1mT hqNAfC7eWlfy9iLk4Mo+vaewNhBcCz+quJ6kXJV84LFzvi1kucBptwaWCXDyW2sc wns8cphNLPopa0xLfYVg4hRellUNy+ypbODkqQHwQH+IoQu6MRNK0iF7v6Ju8py2 qkfblgl8z+4wOaGXAm03A7aedUV8IFpRajMZzRSfH3jmwcb92aVF/Bz1cOo0kGo6 czXcUYXHVPuWUr5gEVqe1g==</SignatureValue> <KeyInfo> <KeyName>C:\Program Files\Common Files\PostureAgent\Plugins\rsakey.pem</KeyName> </KeyInfo> </Signature> </Envelope> If you notice, the first 19 characters in the buffer read in the second time is repeated. For various examples i tried out, i noticed that No. of new lines in the buffer read in the first time = No. of characters repeated during second read operation. Please help me. This sounds to be simple problem, but it is taking a lot of time.
