Encrypted secure Calls with CallProtector!
App available on iOS & Android
With CallProtector you can call others in a secure way, you only need working Internet(EDGE / 3G / WIFI)
While you are calling someone, the devices will be creating a new secret password and the old one gets deleted. This means we are using PFS(Perfect Forward Secrecy), which is a standard for top secret communication.
We use the well known and tested AES 256 algorithm.
This algorithm is normally used for top secret communication.
For creating new passwords we are using ECDH(Elliptic curve Diffie-Hellman) with 521 bitlength.
