ENCRYPTION

FYI uses the most advanced encryption methods to protect your data. Elliptic-curve Diffie–Hellman or ECDHE is a key agreement protocol that allows two parties, each having an elliptic-curve public–private key pair, to establish a shared secret over an insecure channel. The Elliptic Curve Digital Signature Algorithm or ECDSA is a Digital Signature Algorithm which uses keys derived from elliptic curve cryptography. We use ECDHE to securely generate secret encryption keys for each thread and files among parties in the chat. We also employ ECDSA to sign and verify the messages and other critical communications to ensure the sender is who he or she claims to be.
