Encrypted File Engine
Encrypted File Engine: AES-256 File Encryption with Cellular Automata Entropy
Encrypt any file in seconds, no keys to manage. Drop in a PDF, video, spreadsheet, or anything else — AKRUM encrypts it instantly in your browser with quantum-resistant AES-256-GCM, using keys drawn from our Cellular Automata entropy engine mixed with your device's secure random source.
WHAT YOU GET
Quantum-ready by design.
01
Quantum-resistant AES-256-GCM
Client-side encryption. Your bytes never leave the browser unencrypted.
02
Post-quantum protected sharing
Send to another AKRUM user with hybrid ML-KEM-768 + X25519 key encapsulation.
03
Entropy visualizer
Watch Rule 30 chaos generate your keys.
What's new
Post-quantum-ready encryption, built on Cellular Automata entropy
Recent enhancements make AKRUM encryption both quantum-forward and built to adapt — without changing how you use it.
Why quantum-resistant?
Quantum computers threaten key exchange, not strong symmetric encryption. AES-256-GCM is recognized by NIST as secure against quantum attacks, and we protect key exchange separately with post-quantum cryptography.
Post-quantum protected sharing
Share encrypted files to another AKRUM user with hybrid ML-KEM-768 (Kyber) + X25519 key encapsulation, so the shared key survives both classical and quantum attackers. Classical share links remain available for out-of-band key transmission.
Cellular Automata entropy in every key
AES-256 keys are derived through HKDF-SHA-256 from your device's secure random source mixed with AKRUM's Cellular Automata entropy engine. The OS CSPRNG is always the security floor.
Cryptographic agility
Versioned crypto suites let AKRUM roll new algorithms forward without customers redesigning their apps — encrypt today, decrypt tomorrow on whatever suite is current.
Zero-knowledge, client-side
Files are encrypted in your browser with AES-256-GCM before upload. Plaintext bytes never touch our servers.

Contact salesWhat encryption does AKRUM use to protect my files?
+
Files are protected with AES-256-GCM, an authenticated cipher trusted for government and financial workloads. The keys themselves are generated from AKRUM's Cellular Automata entropy engine, not a standard pseudo-random generator.
Where does encryption happen — does my file ever leave my device unencrypted?
+
All encryption runs client-side in your browser. Your bytes are sealed with AES-GCM before anything is sent to AKRUM, so the original plaintext never leaves your device. We only ever see opaque ciphertext.
Can AKRUM or anyone on your servers read my files?
+
No. Encryption happens in your browser and the keys you generate are not retained server-side by default. Without the key you control, the stored package is unreadable ciphertext to AKRUM, our staff, and any attacker who reaches our storage.
Is the encryption post-quantum secure?
+
AES-256-GCM is already considered quantum-safe against currently understood attacks (Grover's algorithm only halves its effective strength, leaving 128-bit security). For AKRUM-to-AKRUM sharing, AKRUM also uses hybrid post-quantum key encapsulation combining ML-KEM-768 (Kyber) with X25519. The Cellular Automata entropy engine feeds standard HKDF-SHA-256 key derivation mixed with the OS CSPRNG.
What file types and sizes can I encrypt?
+
Any file — PDF, MP4, CSV, DOCX, ZIP, images, archives. Free covers files up to 500 MB, Startup 1 GB, Growth 3 GB, and Enterprise 25 GB+ or more on configurable plans. Format does not matter, only size.
Is file encryption free to use?
+
Yes. The Free tier includes 100 encryptions and 100 decryptions per month using rule 30 only, with one-click sharing, the entropy visualizer, and direct in-app downloads. Paid tiers raise limits and unlock the full chaotic rule set.
