We are sure that Usecrypt Messenger is the safest tool available on the market. All encrypting protocols and algorithms that we use, are checked by the best cryptographers and cryptologists. Check the technology that stands behind our app.
UseCrypt Messenger uses advanced cryptographic protocols, that let you constantly check if your phone have been hacked, spied or remotely attacked. The detector in the app will display a red text when the smartphone is in a danger of possible attack.
Your contacts, not our business
When registering, we change your phone number and entire phonebook to crypto abbreviation. There is no way to find it decrypted or guess. We don’t store it either.
We keep a constant bitrate (CBR), while conducting phone calls, which makes it impossible to do a side-channel attack on your device. Usecrypt Messenger also detects man-in-the-middle attacks and informs the user about it (by using Short Authentication String – SAS).
UseCrypt Messenger uses Zimmermann Real‑Time Protocol which negotiates the keys for encryption of two sides of the voice conversation. It uses Diffie–Hellman key exchange and the Secure Real-time Transport Protocol (SRTP) for encryption. By ZRTP you know, if the keys match and if your conversation is secure.
No backups, no problem
Our tool is designed to work only and directly between two users of the app. We don’t store any information about your conversation on our servers, they are in an encrypted sandbox. We don’t do any backups and store no meta-data. It’s impossible to restore any message that were permanently deleted by user.
Yes, we don’t even need to store your IP address, so there is no billings, meta‑data and IP‑geolocation proofs.
Many layers of security
There is no shortcuts in safety; we use independent and separated cypher mechanism for text, voice and video messages.
All of this in the best quality possible for you to talk and chat with the high‑end technology.
We are located in Europe and covered by EU law.
