Binary package “i2p” in ubuntu focal

Invisible Internet Project (I2P) - anonymous network

 I2P is an anonymizing network, offering a simple layer that identity-sensitive
 applications can use to securely communicate. All data is wrapped with several
 layers of encryption, and the network is both distributed and dynamic, with no
 trusted parties.
 This package depends on the router, jbigi, the java service wrapper, and
 includes support to run I2P as a daemon.
