Aspose.PDF.KIT => Verify Digital Signature

Aspose.PDF Product Family
21

Is this still possible with AsposePDF? How can we verify with the public key?

PdfFileSignature.VerifySignature only takes String signName as a parameter.

Hi Tony,


Thanks for your inquiry. Yes, VerfiySignature method takes signature as parameter and returns true if signature is valid. It should work. However for public key verification please share some details about your requirements.

Just check the message in this thread before my comment:

"In the new version of Aspose.Pdf.Kit for Net, we add a interface
:VerifySignature(String signName, String xmlPublicKeyFile) in
PdfFileSignature to support verifing signature using the public key. the
xml public key file can be generated by RSACryptoServiceProvider in
.Net,or it can be generated by other tools only if its’ format is the
same as generated by .Net."

In latest version of AsposePDF the VerifySignature method ONLY takes string signName. I have the same requirements as the original poster. It is no longer possible to verify with the public key?
