End-to-end encryption not even we can read

All messages and files are encrypted on your device before being transferred over the Internet. They can not be decrypted and read before arriving safely at your intended recipient.

No one else has access to your encryption keys. Not even Crypho’s own staff.

Key management and encryption happens automatically. You don't have to worry about safeguarding keys.

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 ElGamal Elliptic Curve Cryptography.

Additionally, all communication runs through SSL/TLS to safeguard against potential man-in-the-middle attacks.
