RSA is a widely used public-key algorithm that relies on a pair of keys — a public key (e) for encryption and a private key (d) for decryption. More information can be found on Wikipedia and Understanding Cryptography Textbook. For testing purposes and to explore how Mathematica handles RSA encryption, I would like to write a small script that encrypts and decrypts data using RSA with small numbers. You can download Mathamatica notebook and also sample output.

I have gathered useful content from various sources and grouped it together for easy reference in resources section.

I continue to stay analog in the digital world, mainly using pen and paper. Besides pencils, I also like to use fountain pens (as well as other types of roller pens). I have tried many inks so far, and Parker Blue-Black QUINK Ink ( Amazon Link) is the best in terms of color, smoothness, and price tag. The deep, rich tone of blue-black provides an elegance that enhances my writing, making even the most everyday notes and draft ideas special.
