Once an individual validates another individual's certificate, what is the use of the public key that is extracted from this digital certificate? The public key is now available to use to create digital signatures. The public key is now available to encrypt future digital certificates that need to be validated. The user can now encrypt private keys that need to be transmitted securely. The user can now encrypt session keys and messages with this public key and can validate the sender's digital signatures.

Transaction Processing

Transaction processing is a computational style generally performed by server computers, which supports interactive applications (apps). Transaction processing is also known as information processing, which divides the work into indivisible and individual operations called transactions. The transaction is a set of tasks; a single task is considered as the minimum processing unit that cannot be divided again.
