About KmxService
Knox Matrix provides a feature to securely generate and store keys used for end-to-end encryption (E2EE). It encrypts/decrypts data on the user’s device and transmits it to the server. The user’s original data cannot be checked as decryption is impossible from the server, which only has encrypted data, and is safely protected from external attacks.
