Vijay Prakash, Deepak Dudeja, Gunjan Chhabra, Lalit Kishore Garg · 2025
The digital era has brought a surge in the amount of data generated, increasing the need for data security across individuals, organizations, and governments. Protecting sensitive information from unauthorized access is a top priority in today&s;s digital world. Cryptography is used to ensure secure communication over the internet, including email, instant messaging, and web browsing. Our paper&s;s primary goal is to develop a cryptography machine capable of encrypting and decrypting different data types, such as plain text, images, audio and videos using the cryptography of the symmetric key. The proposed model will be implemented using Python and Java. Developing the cryptography machine will significantly protect sensitive information and ensure its confidentiality and integrity. The machine&s;s ability to encrypt and decrypt different data types using symmetric-key cryptography will provide an added layer of security to individuals, organizations, and governments in the digital era.
