End-to-end encryption means that all messages and files are encrypted on your device before being transferred over the Internet.

All information transferred or stored is encrypted with AES with random 256-bit keys on your phone or computer before being transferred over the Internet. Crypho’s staff never handles or has access to your keys. Key exchange happens through elliptic curve cryptography (El Gamal ECC). Additionally, all communication runs through SSL/TLS to safeguard against potential man-in-the-middle attacks.
