CryptKey is a free mobile application in early development. We are a non-profit organisation with a privacy-centric focus on the principles of cryptography. CryptKey hopes to offer the public a convenient platform for secure communication exchange.

Soon to be available on Android

Requirements: Compatible with the xNT implantable RFID tag from DangerousThings. Requires an Android device running 5.1.1 Lollipop or later.

End-to-End Encryption

Data is transmitted in encrypted format between our servers and user devices. Messages between CryptKey users are transmitted in encrypted form within our secure server network. Because data is encrypted at all stages, the risk of message interception is largely eliminated. This ensures only you and the person you're communicating with can read what is sent, and nobody in between, not even CryptKey.

Zero Access to User Data

Our segregated authentication and decryption system means using CryptKey requires two authentication measures. The first is a password used to validate cognitive consent of user access. The second is physical authentication using the xNT implant. These measures combined are capable of decrypting and authenticating user data locally, meaning no data is ever sent to us in a intelligible form. This means we cannot hand over your data to third parties.

Open Source Cryptography

We use only secure implementations of AES, RSA, and ECDH. Furthermore, all of the cryptographic libraries we use are open source. By using open source libraries, we can guarantee that the encryption algorithms we are using do not have clandestinely built in back doors. CryptKey's open source software has been thoroughly vetted by security experts from around the world to ensure the highest levels of protection.

Easy to Use

Our design concept offers an exclusive platform that bridges the gap between privacy and convenience. We’ve taken a number of complicated cryptographic frameworks, and applied them to a unique easy-to-use design concept offering secure communication exchange between two or more parties. Our app inherits many features from some of the most commonly used social media applications today providing a convenient and straightforward user interface layout.
