MATLAB-Based Software with Interactive Interface for RSA Encryption and Decryption

This software is an interactive application developed using MATLAB that specializes in RSA encryption and decryption functionality. The system implements core RSA algorithms including prime number generation using MATLAB's isprime() function, key pair creation through modular arithmetic operations, and encryption/decryption processes utilizing powermod() for efficient large-number calculations. The intuitive GUI interface allows users to input plaintext messages, generate public/private keys automatically, and visualize the encryption/decryption pipeline without requiring deep algorithm knowledge. All MATLAB source code is thoroughly commented, demonstrating practical implementations of Euler's totient function, extended Euclidean algorithm for private key calculation, and ASCII conversion routines for text processing. Both beginners and experienced users can leverage this tool to strengthen their understanding of asymmetric cryptography through hands-on experimentation with complete MATLAB code examples that cover error handling, input validation, and cryptographic best practices.
