- 1.What is an electronic signature?
An electronic signature is a tool for identification and authentication in the Internet environment.
It is electronic data that is a digital alternative to the so-called officially certified signature (a signature on a document whose authenticity has been verified by an administrative authority). This small piece of special data is attached to an electronic document and is used to verify the identity of the sender.
An electronic signature can be imagined as such invisible data attached to a file. The program in which the signed electronic document is viewed by the user only alerts him in various ways that there is an electronic signature.Note
If you print the electronically signed document, the electronic signature will not be there. Such a printed document is no longer signed, even though "nothing has disappeared" from it.
