While working on a project, we recently came across a requirement to be able to digitally sign pdf documents in C# code using a public/private key pair and later be able to verify the signature. Basically we were working on an online e-Tendering portal for a semi-government organization. The organization wanted to accept documents from its Vendors online through a portal and be able to verify that the documents indeed originated from a particular Vendor.
