One more point....
My certificate and private key shows the singature algorithm as SHA1withRSA
and the providew is also not BC. So, how i can instatiate the PdfPKCS7
object while signing the pdf. any updates needs to be done or extra steps
needs to be followd to create the correct instance of PdfPKCS7 classs while
sigining the pdf. May be because of this my verification is failing.
Curently while signing the PDF i am using the followign line of code:
PdfPKCS7 sgn = new PdfPKCS7(privateKey, certChain, null, "SHA-1",
"HSMDevice JCA Provider name", true);
when i m passing the SHA1withRSa instead of SHA-1 its failing. So, please
let me know the right thing to be able to pass here as SHA1 with RSA.
thanks
