Thanks for the references, SForrest96. I went through the documentations of these open-source utilities but I am still at lost as to how I can integrate it with my own project. To give you a basic understanding of what I'm doing, I have a website (.Net C#) that hosts interactive PDFs (created using LiveCycle Designer). Each form can be submitted online. With the submission, I would like to authenticate the request by allowing the user to digitally sign the form. But since not all users will have certificates, I would like to automate the process so that upon creation of their accounts a certificate (maybe self-sign digital ID) is created for them and maybe store those certificates somewhere in our application server or database.
