# Alpenhorn

Alpenhorn is the first system for initiating an encrypted connection

between two users that provides strong privacy and forward secrecy

guarantees for **metadata**. Alpenhorn does not require out-of-band

communication other than knowing your friend's Alpenhorn username

(usually their email address). Alpenhorn's design, threat model, and

performance are described in our

[OSDI 2016 paper](https://davidlazar.org/papers/alpenhorn.pdf).

In short, Alpenhorn works well for bootstrapping conversations in

[Vuvuzela](https://github.com/vuvuzela/vuvuzela). Now users can start

chatting on Vuvuzela without having to exchange keys in person or over

some less secure channel.

A beta deployment of Alpenhorn and Vuvuzela is coming soon.
