This looks like an academic major project exploring one of the more elegant corners of applied cryptography: image encryption using chaotic maps combined with a scan pattern technique. The repo name alone tells you the author committed to a specific, well-defined problem rather than a vague "encryption tool" — and that specificity is what makes it worth a look.
The underlying idea is genuinely interesting. Traditional block ciphers like AES were designed for text and structured data, but images have properties (strong pixel correlation, bulk data, redundancy) that make purpose-built schemes attractive. Chaotic maps — think logistic maps, Arnold's cat map, or Chen's system — produce pseudo-random sequences that are:
Pairing that with a scan pattern — a deterministic path through the pixel grid (zigzag, spiral, Hilbert curve, etc.) — gives you the confusion step: pixels are permuted along the scan path before or after the chaotic XOR/substitution stage.
Who might find this useful:
The caveat: chaotic-map image encryption is a well-trodden research area with known attacks against naive constructions, so this shouldn't be used for anything real. But as a learning artifact — showing the interplay between dynamical systems, permutation, and diffusion — it's the kind of undergraduate project that teaches more about cipher design than reading another AES tutorial.
