Information technology is becoming wider spread started to develop the digital signature also. More countries, including Hungary, permit the use and the adoption of the digital signature. The actuality of my thesis was caused by the emergence of new identity cards, as the identity cards issued from 2016, contain a certificate issued to the citizen. The citizen may sign documents with this certificate, what he/she prove his/her own signature, that he/she signed, not someone else, and which is available to send the document including his/her own signature.
I make a theoretical overview of the digital signature theme important concepts with which it comes mention of the subject.
After the theoretical overview, I plan an application that is capable of forming digital signatures and their verification.
Then comes the implementation part based on these plans, which will be implemented by a usable software. This software is a prototype, which covers that you will not have a user interface, but there will be a console application.
