when i was a kid , i used to think that digital signature is just signature in Digital form(picture of signature). but i was wrong at all.
it's use is just the same like Normal signature (i.e to validate something) but form is different (i.e. digital)
so the definition of digital signature can be "A digital signature is a mathematical scheme for verifying the authenticity of digital messages or documents"
Digital signature has following prerequisites.
