The data stream between two users is encrypted using the AES algorithm (using 256-bit key length), and a new key is generated for each session (call).
The key exchange is made based on the ZRTP protocol (using the ECDH-384 algorithm) which offers protection against Man in The Middle attacks.
The exchange of the keys is made between users mobile terminals, without involving any 3rd party.

Share your public key with your friends in two ways:
- Auto: ask the application for sending your public key to a contact chosen from the address book; if he has already installed the application you will receive his public key automatically.
- Manual: export your public key as text or file and shares with your device share alternatives (e.g., mail, simple text messages, multimedia text messages)
Each encrpyted message received is automatically decrypted and organized in conversation according to the contact that has sent it.
All the messages that you receive are stored in a password protecte memory area.
