A lightweight encryption tool for secure communication between two parties. One numeric seed generates one unique cipher. Encrypt text messages or any files (images, documents, archives).
- Enter a numeric seed (e.g.,
8374920158) or generate a random one - Share this number with your contact
- Identical seeds produce identical ciphers
- For files: the seed is embedded in the
.encfile, so the recipient doesn't need to type it
- Deterministic seed-based cipher generation
- Full Unicode support (Cyrillic, Latin, digits, special characters)
- Text encryption (substitution cipher)
- File encryption — images, documents, any file type (XOR gamma)
- Seed verification when decrypting files
- Drag & Drop files onto the window
- File picker dialog (Select File...)
- Save dialog to choose where to save encrypted/decrypted files
- Dark/light theme toggle
- Resizable window with fullscreen support
- Seed strength indicator (red/yellow/green)
- Copy output or seed to clipboard
- Hotkeys: Ctrl+E (Encrypt), Ctrl+D (Decrypt)
- Portable — single .exe, no installation, works offline
