SendOtherSocials: Encryptor

Create your own end-to-end encryption - no servers, no sign-ups. Turn text into emoji or Chinese-character sequences that look harmless - but can only be read with the right key. Files (photos, documents, archives, and more) are encrypted locally on your device and can be safely sent anywhere. ✨ What the app can do: ✦ 3 text encryption modes: • Chinese characters • Emojis • Cryptographic mode (Threefish-1024, Base91 output) Transform any message into Chinese characters, emojis, or cryptotext. A simple phrase like “Hello!” turns into a sequence of characters that no one can read without the key. ✦ Local key storage - save your keys, switch between them instantly, no need to re-enter. ✦ Post-quantum key exchange - supports Kyber ML-KEM-512 and ML-KEM-768 for each contact; you can store multiple keys per contact, no limits. ✦ File encryption for any file type. Protect photos, documents, archives, and any other data. Even when sent via messengers or social networks, they stay fully secure. ✦ End-to-end in your hands: only you and the recipient know the key. ✦ 69+ UI languages - convenient worldwide. ✦ Built-in secure keyboard for safe, third-party-free input (Latin and Cyrillic). ✦ Your key = your imagination: any text, symbols, or favorite emojis. ✦ No accounts, no servers - everything works locally on your device. 🛡️ Security modes ● Deterministic - the same text always produces the same ciphertext. Useful for predictability and searching over encrypted data. ● Non-deterministic - the same input and key produce different ciphertexts each time. More randomness means higher resistance to analysis. 🔐 Key and data protection ● All keys and shared secrets are stored locally in an encrypted database (SQLCipher). ● The database passphrase is additionally protected via Android Keystore. ● User-entered keys are encrypted again (AES-GCM) before being stored and are bound to a specific contact and alias. ● Nothing is sent to external servers - you share public parts or shared secrets only through channels you choose. 🚀 In practice ➤ Send your friend a phrase encrypted as emojis - for everyone else it’s just a cute set of symbols, but for you two it’s a secret message. ➤ Agree on a key via Kyber and keep encrypting without typing keys manually. ➤ Encrypt a document and upload it to the cloud or send it in a messenger - even if it leaks, it can’t be opened without the key. ⚡ Why it’s convenient ✔ Original text disguise (emoji / Chinese characters) + a Threefish-1024 cryptographic layer. ✔ Post-quantum key exchange (Kyber ML-KEM-512 / 768) - future-proof security. ✔ Simple and fast: enter text or pick a file → encrypt → send. ✔ You control the key. ❗ Important The app improves privacy and protects data when used correctly and when the key is stored safely. Files are encrypted using the Threefish algorithm (BouncyCastle implementation). ⚠️ Some apps or services may not display emoji- or Chinese-based ciphertext correctly. Before sending, check whether the recipient can see the characters.
