Dark Message — encrypt messages and files without the internet Write the way you always do: in any messenger, in mail, in social networks. Dark Message turns text, photos and documents into an encrypted message that only the holder of the same key can read. Anyone who intercepts it sees a string of characters. WHY DARK MESSAGE • Fully offline. The app has no internet access at all: no servers, no accounts, no sign-up, no analytics. Keys and messages never leave your phone. • Strong encryption: AES-256-GCM, with the key derived from your passphrase by PBKDF2-HMAC-SHA512 (600,000 iterations). • Works over any channel: copy the encrypted text and paste it anywhere. .darkm files travel as ordinary attachments. • Encrypts more than text: photos and documents (PDF, Word, Excel, any file), keeping the file name. A KEY IN SECONDS • Show a QR code and read out a six-digit PIN. The key inside the code is encrypted with that PIN, so a photo of the screen is useless to anyone else. • A key fingerprint next to every chat: the same on two phones means the same key. EASY TO USE • A separate key for every contact or group. • One-tap decryption: paste the text or open the file. • Dark and light themes, English and Russian. • Passphrases live in the system keychain. WHO IT IS FOR Private conversations, business documents, contracts, medical and financial records, family passwords — anything nobody but the recipient should read. Open source: you can check for yourself how it works. Updates keep all your chats and keys.
