Local-only
desktop file
encryption.
CRYpT encrypts files on your machine with a 14-cipher AEAD cascade and double Argon2id key derivation. Open source under MIT. No cloud, no key escrow, no telemetry. The studio shipped it, learned what local-only privacy primitives feel like, then moved that thinking into VIGIL's on-prem story.
14 ciphers. One file. No single point of failure.
Five primary ciphers
AES-256-GCM, ChaCha20-Poly1305, Serpent, Twofish, Camellia. Each layer authenticated. Compromising any one cipher leaves the cascade intact.
192-round network
Custom 192-round Feistel network across the remaining nine block functions. Diffusion well past standard cryptanalysis budgets.
Double Argon2id
Memory-hard, tunable cost. Two independent Argon2id passes with separate salts. Brute-force assumes you have the passphrase already.
Privacy is
an architecture,
not a feature.
CRYpT was the studio's argument that local-only encryption should be the default, not the premium tier. Free for the entire base feature set; the Pro tier ($14, one-time) adds batch encryption and metadata wiping. The codebase stays open under MIT.
The studio doesn't actively develop CRYpT anymore. The architectural lesson (no cloud, no escrow, local-first by default) carried over into VIGIL's desktop mode. If you want to use CRYpT, download it; if you want to maintain it, fork it.
