The I2P network uses a public/private key pair for endpoint identity.  The keys that Tixati will use for it's peer connections and DHT messages is set from this dialog, which can be found in Settings > I2P.


The host name is derived from the Ed25519 public key that is generated from the base32 encoded private key.  I2P does not directly use the public key as host name.

On Desktop systems, there is a Find button which will launch a vanity host-name finder.
