The process of digitally signing starts by taking a mathematical summary (called a hash code) of the check. This hash code is a uniquely-identifying digital fingerprint of the check. If even a single bit of the check changes, the hash code will dramatically change. The next step in creating a digital signature is to sign the hash code with your private key. This signed hash code is then appended to the check. How is this a signature? Well, the recipient of your check can verify the hash code sent by you, using your public key. At the same time, a new hash code can be created from the received check and compared with the original signed hash code. If the hash codes match, then the recipient has verified that the check has not been altered. The recipient also knows that only you could have sent the check because only you have the private key that signed the original hash code.

A computerized mark is a scientific plan for showing the realness of advanced messages or archives. A legitimate advanced mark gives a beneficiary motivation to trust that the message was made by a known sender (verification), that the sender can't deny having sent the message (non-revocation), and that the message was not adjusted in travel (honesty). Advanced marks are a standard component of most cryptographic convention suites, and are usually utilized for programming appropriation, monetary exchanges, contract administration programming, and in different situations where it is vital to recognize imitation or altering.
