I would like to sign PDF from remote server. I don’t want to send the entire file through internet.
Here is my use case :
- Windows application select file to sign
- Application compute hash file
- Hash is sent to remote server
- Server generate signature and send it back to application
- Application add generated signature to pdf
I found an example to do it with itextsharp : https://stackoverflow.com/questions/43304062/pdf-signature-embed-separatly-signed-hash
I want to do this process with aspose, how can i do ?
