4Krypt is the project behind OMNI-512
To create a "better" encryption for the post-quantum era, I have designed OMNI-512. It is an Authenticated Encryption with Associated Data (AEAD) cipher that conceptually exceeds AES-256 specs:
-
512-bit Block Size: Quadruple the size of AES (128-bit). This renders "birthday attacks" (collisions) statistically impossible even with exabytes of data.
-
1024-bit Key: Exceeds military-grade requirements. Even if a Quantum Computer halves the effective strength, you are left with 512 bits of entropy—far beyond the estimated total energy of the universe required to brute force.
-
Dynamic S-Boxes: Unlike AES, which uses a static Substitution Box (known to attackers), OMNI-512 generates a unique, key-dependent S-Box for every session. This defeats pre-computed differential cryptanalysis attacks.

Structure: A 20-Round Substitution-Permutation Network (SPN) using "ARX" (Add-Rotate-XOR) methodology for speed and diffusion.
