How to implement an electronic signature of a document on the site?

Question

Electronic digital signature

Ask a question, maybe someone knows. The client has an electronic signature issued by a certification authority. The site has an electronic contract. It is necessary if the client is ready to conclude an agreement, he enters his data into the form and presses the "sign" button, after which the agreement is combined with the client's data, signed and sent to the database and to e-mail. Here is the question of how to implement directly the very signing of the contract on the button (including checking the validity of the signature)?
