How does the generation and verification process work for the ElGamal Digital Signature, if you don't mind my asking?

Why does authentication still cause so much worry in this era of ubiquitous digital verification?

Do you believe that it is feasible to build a bogus digital signature that is based on the RSA algorithm? Please explain why you either agree or disagree with the statement, regardless of which camp you fall into.

What does it mean precisely when something is signed digitally, and how does the process work in practise? When it comes to digital signatures, what precisely differentiates digital signatures from electronic signatures is the difference between digital signatures and electronic signatures? In order to establish your viewpoint, you must present actual instances.
