In this paper, the authors used the stream cipher which is the best way with the algorithm Geffe generator with a specific length to encryption the information from plain text in the first compute.

This paper presents a design of data encryption and decryption in a network environment using RSA algorithm with a specific message block size.

Encryption is essential for protecting data, with both symmetric and asymmetric methods offering unique advantages.

This algorithm was provided for completeness. IDEA International Data Encryption Algorithm was produced by Xuejia Lai and James Massey.

The quantum computing decryption threat will be here soon enough, and it is time for businesses, organizations and governments to protect their data for that inevitability.

Cryptography is the art of keeping information secret and safe by transforming it into form that unintended recipients cannot understand. It makes secure data transmission over the internet possible.

With experts suggesting that quantum computers will decrypt public key algorithms by 2030, quantum risk cryptography is becoming vital.
