Cryptography

Cryptography, or cryptology is the practice and study of techniques for secure communication in the presence of adversarial behavior. More generally, cryptography is about constructing and analyzing protocols that prevent third parties or the public from reading private messages.

https://github.com/seigr-lab/seigr-ecosystem

Inspired by biomimicry, Seigr is a Symbiotic Environment of Interconnected Generative Records. This decentralized network enables secure data capsules, adaptive encoding, and dynamic traceability across decentralized storage layers, including IPFS. Anchored by the .seigr protocol, it fosters resilient, modular, and sustainable data management.

In developing a secure client-server model, we implement the Advanced Encryption Standard (AES) and a hashing algorithm from scratch. The AES implementation includes key expansion, key-mixing operations, and secure modes like Cipher Block Chaining (CBC). For hashing, we choose SHA-256 and ensure its resistant to common cryptographic attacks.
