Algo (short for "Al Gore", the Vice President of Networks everywhere for inventing the Internet) is a set of Ansible scripts that simplifies the setup of an IPSEC VPN. It contains the most secure defaults available, works with common cloud providers, and does not require client software on most devices.

Usage

Open the file config.cfg in your favorite text editor. Change server_name and specify users in the users list.
Start the deploy and follow the instructions:

ansible-playbook deploy.yml

When the process is done, you can find .mobileconfig files and certificates in the configs directory. Send the .mobileconfig profile to your users on iOS or macOS (note: Profile installation is supported over AirDrop) or send the X.509 certificates to those using other clients, like Windows or Android.
When the deploy proccess is done a new server will be placed in the local inventory file inventory_users.
If you want to add or delete users, update the users list in config.cfg and run the playbook users.yml. This command will update users on all the servers in the file inventory_users. If you want to limit servers it updates, you can use -l flag.

ansible-playbook users.yml -i inventory_users
ansible-playbook users.yml -i inventory_users -l example.com

FAQ

Has this been audited?

No. This project is under active development. We're happy to accept and fix issues as they are identified.

Why aren't you using Tor?

The goal of this project is not to provide anonymity, but to ensure confidentiality of network traffic while traveling. Tor introduces new risks that are unsuitable for algo's intended usesrs. Namely, with algo, users are in control over the gateway routing their traffic. With Tor, users are at the mercy of actively malicious exit nodes.
