2. The establishment of a secure communication between two communicating parties is becoming an issue due to the likelihood of attacks and other unintentional changes during an active communication over an unsecured network. Cryptography is one of the security measure used for data integrity, entity authentication, data origin authentication, and non- repudiation. Demonstrate with explanation ONE (1) complete cycle of message transformation from a string of plaintext to a string of ciphertext by using any cryptographic techniques with suitable algorithm of your choice. * The demonstration must be supported with 1 sample of plaintext, correct technical flow of plaintext transformation, with 1 final correct ciphertext coming from the transformation.
