Pigpen Cipher in Computer Science

The Pigpen Cipher is a simple substitution cipher that replaces letters with geometric symbols based on a structured grid. It is an introductory concept in cryptography and symbolic encoding.

How the Pigpen Cipher Works

The Pigpen Cipher divides the alphabet into structured grids:

Tic-Tac-Toe Grid

Second Grid

X-Shaped Grid

Computational Perspective

• Cryptography: Introduces monoalphabetic substitution ciphers.
• Symbolic Encoding: Demonstrates character-to-symbol transformation.
• Programming: Easily implemented using lookup tables or dictionaries.
