PhoneX - Secure communication app for iPhone and iPad

Solution for the secure communication, encrypted calls, encrypted messages and file transfer. Secure communication for individuals and companies.

Application features:
* Truly secure private messaging and voice calls with military grade encryption.

* No telephone number or email is required. System operates just with your nick name.

* Encryption happens directly in the phone, end-to-end.

* Your messages are stored in the encrypted form. Nobody can read it without encryption password.

* Passcode protection. On 3 failed attempts encryption keys are discarded, user is logged out. Encrypted database is locked and protected.

* PhoneX protects your calls and messages using a strong symmetric and asymmetric cryptography thus no one else can see your private data.

* Unique encryption keys generated on demand, Diffie-Hellman protocol.

* Call encrypted by AES-256, for each call a new unique password is generated. Password is destroyed after call finishes.

* Messages protected by RSA-2048, AES-256. We are implementing TextSecure soon.

* Server does not see your data. Server administrators are unable to read your messages or listen to your calls. No eavesdropping is possible. Server acts only as a rendezvous party, introducing one PhoneX user to another.

* Voice calls are routed directly peer-to-peer, without server, if possible. In case of a strict firewall, simple relay server is used. Relay server is unable to decrypt data as only caller and callee have the encryption key.

* Contact list is separated from the system contact list.

* Secure encrypted storage for messages, call logs and contacts.

* Can be used in untrusted networks, such as free WiFi hotspots.

* PhoneX does not collect your personal data.

Description:
Calls happen directly between phones, server is used only for the call initialization. ZRTP is used as key-agreement protocol to negotiate the keys for symmetric encryption (AES-256, Twofish) before the call is established. Keys are unique for each call and dropped right after call finishes.

End-to-end security provided by end user certificates, end-to-end privacy and authentication for your security.
Active product development and support is provided.
