89crypt: Matrix-Based Encryption

August 2025 | Python, Cryptography, Math

89crypt offers a mathematical approach to symmetric encryption distinct from conventional cryptographic algorithms. It leverages repeating decimal expansions to populate key matrices.

Objective & Achievements

  • Mathematical Innovation: Uses periodic decimal expansions for matrix-based encryption.
  • Robust Engineering: Fully type-hinted Python package with modular design and comprehensive documentation.
  • Recognition: Finalist in the I-MAT Project Competition and TUBITAK 2204-A participant.
  • Open Source: Published under GPL-3.0 to encourage transparency and collaboration.

The project demonstrates high-level proficiency in software architecture, mathematical modeling, and cryptographic principles.
