But cannot mathematicians use somebody's general public key to somehow calculate what the matching non-public essential is?

Almost, since there's nothing 'individual' still concerning the hash. It is an antiseptic mathematical course of action. File --> (crunch) --> hash. This hash goes with this particular Digital file (and with no other file that anybody can discover). But Let's say the hash of the concept was encrypted with Kevin's mystery crucial? The hash is a brief issue, and straightforward for RSA to encrypt. No waiting. What if Kevin sent his information along with the encrypted hash together with it? What could Tanya make of that? Well, her software program could re-work out the hash with the message which has arrived on her screen. It could be exactly the same hash that Kevin's software had calculated (delivered the message hadn't been modified.) Following Tanya's application would decrypt the encrypted hash that arrived with the message. The truth that the software program could decrypt it with Kevin's community vital proves it came from Kevin. And the fact that the hash that is exposed matches the hash that Tanya's program just computed proves the information is similar that Kevin despatched. All performed. QED, you could possibly say. So a digital signature is made such as this: File --> (crunch) --> hash --> (encrypt with personal key) --> digital signature. The digital signature can be individual through the file, or tacked on at The underside. This is a separated digital signature made by me: -----BEGIN PGP Concept-----
