Quintrophy1x – A Quantum-Proof Cipher That Leaves AES-256-GCM in the Dust

[retrocryptid]

I couldn't find reference to quintrophy or quintrophy1x in the IACR eprint archive (or on a google search.) And I think you forgot the references to external review.

Thanks for your comment! As this is a brand-new project, it hasn’t been submitted to the IACR ePrint Archive yet, and there’s no prior mention of it there or in broader searches, being that it’s a fresh release. We built this as an original implementation to push the boundaries of encryption strength with a 512-bit key and custom transformations, and I’m excited to share it with the community here first.

With a 512-bit key and 16 rounds operating on 128-byte blocks, Quintrophy1x integrates dynamic substitution, key-driven permutations, fractional bit mixing, and inter-block diffusion to create a quantum-proof cipher that's stronger than AES-256-GCM.

Interesting. You use Fisher-Yates extensively. How do you feed it ?

Quintrophy1x has been appropriately renamed as, Quintropy1x. This aligns better with the Quintessentropy suite as well as succeeding it's purpose in delivering quintessential entropy on every encryption.
