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/venkat-kolasani/knight-s-tour-based-cryptographic-key-generation

The Knight's Tour Encryption System is a cryptographic application that leverages the Knight's Tour problem on a chessboard to generate a unique encryption key. This key is then used for XOR-based encryption and decryption of messages.
