Hi
I created an experimental encryption algorithm called QARX-256 as a learning project.
It’s a symmetric block cipher based on ARX (Add–Rotate–XOR) with:
- 256-bit block size
- 512-bit key size
- Hash-based key schedule
- Designed with post-quantum considerations in mind
This is NOT for production use. It’s purely experimental and for learning cryptographic design.

I’d appreciate any feedback, critique, or suggestions on the design.
Thanks!
