Encryption and Decryption Process
Encryption is the operation of transforming a message (referred to as plaintext) to a cryptogram, which is a set of symbols unreadable to anyone except those possessing the readable key. The transforming process must be reversible and allow, therefore, to reconstruct the previously encrypted message when the readable key is available.
The encryption process takes place through the use of algorithms, complex mathematical functions that are applied to the message and make it unreadable without the decryption key.
The encryption and decryption process can be described as follows:
