Cipherise™ is a mobile application that implements a zero-trust, end-to-end encrypted communication protocol to securely and anonymously exchange secrets between two parties. It is the first application of its kind to implement this protocol in the mobile space.

The secret-exchange process is simple and requires only the exchange of a single secret between two parties that are physically separated. Each party can be an individual person or a group of people that work together.

The two parties can be located anywhere in the world and need not be in the same country.

This encryption protocol is based on the principles of public-key cryptography and secret-key cryptography.
