 ## Notable Features
 - Coordination-less globally unique adressing and identification
 - Fully self-configuring multi-hop routing
- - Asymmetric RSA encryption and signatures as basis for all communication
- - Perfect Forward Secrecy on links with ephemereal Elliptic Curve Diffie-Hellman keys (on Curve25519)
- - Reticulum uses the [Fernet](https://github.com/fernet/spec/blob/master/Spec.md) specification for encryption on links and to group destinations
+ - Asymmetric X25519 encryption and Ed25519 signatures as a basis for all communication
+ - Forward Secrecy with ephemereal Elliptic Curve Diffie-Hellman keys (on Curve25519)
+ - Reticulum uses the [Fernet](https://github.com/fernet/spec/blob/master/Spec.md) specification for encryption
    - AES-128 in CBC mode with PKCS7 padding
    - HMAC using SHA256 for authentication
    - IVs are generated through os.urandom()
+    - Keys are ephemeral and derived from an ECDH key exchange on Curve25519
 - Unforgeable packet delivery confirmations
 - A variety of supported interface types
 - An intuitive and easy-to-use API
