Is there a standard implementation of electronic signatures on web applications with filling out a form?

Question

I have a client who is interested in adding electronic signature support to a seller’s long application (40 questions). I am a little fixated on whether there is an existing standard or process that people in the financial world would expect to see there?

I could, of course, add a system in which we create a bunch of text based on their answers, ask the applicant to sign it with his private key and download the public key, but this is very similar to the question of people. Not even PGP currently installed nrds?

Is there a standard approach to this? Does anyone work in the financial world that did this and did it work well?

Answer 1

What purpose is the signature trying to fill out? Are you trying to verify that the form was actually received from a particular seller? (If so, you will need to know their public key ahead of time.) Are you trying to get the seller to answer for your answers later? (In this case, you may need some kind of third party.)

Sometimes people ask for electronic signatures just because they sound neat.

With closed environments (such as functionaries, doctors ...) where all users are suing for certificate storage (with trust trusted by CA), and you must be sure that the form is submitted by someone trusted (no response), integrity ...) this is the best scenario for signing a form, otherwise I do not recommend you use signed forms to achieve your goal.
