Encryption
Offline File Encryptor & Decryptor
Armor any binary or document offline with passphrase-derived AES-256 keys. No data touches the wire; operations happen in WebAssembly workers.
Select file to encrypt
Accepts any file type (documents, archives, photos)
Warning: Synthesis Cyber has zero backdoor access. If you lose this passphrase, your file cannot be recovered.
This module is guided content rather than a processing tool. It walks you through steps on the systems you already use, and nothing about your setup is sent to us.
No single tool makes an account or a device secure. This module reduces one specific category of risk. It does not detect malware already running on your device, it cannot recover data you lose the key to, and it does not replace keeping software updated and using unique credentials everywhere.
If your device itself is compromised, anything you type into any tool — including this one — can be observed. Treat device hygiene as the foundation everything else sits on.
