Algo

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.

Supports only AES GCM, SHA2 HMAC, and P-256 DH
Generates mobileconfig profiles to auto-configure Apple devices
Provides helper scripts to add and remove users
Blocks ads with an included HTTP proxy (optional)
Based on current versions of Ubuntu and StrongSwan

Anti-features

Does not support legacy cipher suites or protocols like L2TP or IKEv1
Does not install Tor, OpenVPN, or other insecure servers
Does not require client software on most platforms
Does not claim to provide anonymity
Does not claim to protect you from the FSB, MSS, DGSE, or FSM

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 users. 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.
