58 billion trillion trillion years to brute-force
FORTRESS mode forces 2 GB of RAM and 64 Argon2id iterations per password guess. At one trillion guesses per second, exhausting a 14-character key space takes ~5.8 × 1031 years — longer than the universe has existed, squared.
How It Works
CRYpT doesn't just encrypt your files — it generates a unique cipher pipeline for every key. The algorithm itself is the secret.
Breaking any single layer — AES-256, XChaCha20, or the 192-round Feistel — would be the greatest cryptanalytic achievement in human history. CRYpT stacks all 14.
The cipher pipeline is derived from your key. The algorithm itself is secret. No two encryptions follow the same path.
FORTRESS demands 2 GB RAM per guess. A $100 M GPU cluster running 24/7 burns through its budget before finishing a single percent of the key space.
Three passes of 64 rounds each through a BLAKE2b-256 Feistel network. The asteroid that killed the dinosaurs carried 4 × 1023 joules — nowhere near the energy needed to brute-force 192 rounds.
Standard (free), Military (free), Paranoid (Pro), and FORTRESS (Pro) — escalating layers of protection for any threat model.
Windows installer (.msi), no browser required. Your files never leave your machine. Fully offline encryption.
Every encryption generates a 256-byte (2048-bit) random salt — a 617-digit number. The observable universe contains ~1080 atoms. CRYpT's salt space is 10617. That's more possible salts than atoms in 10537 universes.
