It uses the most secure defaults available, works with common cloud providers, and does not require client software on most devices. See our [release announcement](https://blog.trailofbits.com/2016/12/12/meet-algo-the-vpn-that-works/) for more information.\n\n## Features\n\n* Supports only IKEv2 with strong crypto (AES-GCM, SHA2, and P-256) and [WireGuard](https://www.wireguard.com/)\n* Generates Apple profiles to auto-configure iOS and macOS devices\n* Includes a helper script to add and remove users\n* Blocks ads with a local DNS resolver (optional)\n* Sets up limited SSH users for tunneling traffic (optional)\n* Based on current versions of Ubuntu and strongSwan\n* Installs to DigitalOcean, Amazon Lightsail, Amazon EC2, Microsoft Azure, Google Compute Engine, Scaleway, OpenStack or your own Ubuntu 18.04 LTS server\n\n## Anti-features\n\n* Does not support legacy cipher suites or protocols like L2TP, IKEv1, or RSA\n* Does not install Tor, OpenVPN, or other risky servers\n* Does not depend on the security of [TLS](https://tools.ietf.org/html/rfc7457)\n* Does not require client software on most platforms\n* Does not claim to provide anonymity or censorship avoidance\n* Does not claim to protect you from the [FSB](https://en.wikipedia.org/wiki/Federal_Security_Service), [MSS](https://en.wikipedia.org/wiki/Ministry_of_State_Security_(China)), [DGSE](https://en.wikipedia.org/wiki/Directorate-General_for_External_Security), or [FSM](https://en.wikipedia.org/wiki/Flying_Spaghetti_Monster)\n\n## Deploy the Algo Server\n\nThe easiest way to get an Algo server running is to let it set up a _new_ virtual machine in the cloud for you.\n\n1. **Setup an account on a cloud hosting provider.** Algo supports [DigitalOcean](https://m.do.co/c/4d7f4ff9cfe4) (most user friendly), [Amazon Lightsail](https://aws.amazon.com/lightsail/), [Amazon EC2](https://aws.amazon.com/), [Microsoft Azure](https://azure.microsoft.com/), [Google Compute Engine](https://cloud.google.com/compute/), [Scaleway](https://www.scaleway.com/) and [OpenStack](https://www.openstack.org/).\n\n2. **[Download Algo](https://github.com/trailofbits/algo/archive/master.zip).** Unzip it in a convenient location on your local machine.\n\n3. **Install Algo's core dependencies.** Open the Terminal. The `python` interpreter you use to deploy Algo must be python2. If you don't know what this means, you're probably fine. `cd` into the `algo-master` directory where you unzipped Algo, then run:\n\n - macOS:\n ```bash\n $ python -m ensurepip --user\n $ python -m pip install --user --upgrade virtualenv\n ```\n - Linux (deb-based):\n ```bash\n $ sudo apt-get update && sudo apt-get install \\\n build-essential \\\n libssl-dev \\\n libffi-dev \\\n python-dev \\\n python-pip \\\n python-setuptools \\\n python-virtualenv -y\n ```\n - Linux (rpm-based): See the [Pre-Install Documentation for RedHat/CentOS 6.x](docs/deploy-from-redhat-centos6.md)\n - Windows: See the [Windows documentation](docs/deploy-from-windows.md)\n\n4. **Install Algo's remaining dependencies.** Use the same Terminal window as the previous step and run:\n ```bash\n $ python -m virtualenv --python=`which python2` env &&\n source env/bin/activate &&\n python -m pip install -U pip &&\n python -m pip install -r requirements.txt\n ```\n On macOS, you may be prompted to install `cc`. You should press accept if so.\n\n5. **List the users to create.** Open `config.cfg` in your favorite text editor. Specify the users you wish to create in the `users` list.\n\n6. **Start the deployment.** Return to your terminal. In the Algo directory, run `./algo` and follow the instructions. There are several optional features available. None are required for a fully functional VPN server. These optional features are described in greater detail in [deploy-from-ansible.md](docs/deploy-from-ansible.md).\n\nThat's it! You will get the message below when the server deployment process completes. You now have an Algo server on the internet. Take note of the p12 (user certificate) password in case you need it later, **it will only be displayed this time**.\n\nYou can now setup clients to connect it, e.g. your iPhone or laptop. Proceed to [Configure the VPN Clients](#configure-the-vpn-clients) below.\n\n```\n \"\\\"#----------------------------------------------------------------------#\\\"\",\n \"\\\"# Congratulations! #\\\"\",\n \"\\\"# Your Algo server is running. #\\\"\",\n \"\\\"# Config files and certificates are in the ./configs/ directory. #\\\"\",\n \"\\\"# Go to https://whoer.net/ after connecting #\\\"\",\n \"\\\"# and ensure that all your traffic passes through the VPN. #\\\"\",\n \"\\\"# Local DNS resolver 172.16.0.1 #\\\"\",\n \"\\\"# The p12 and SSH keys password is XXXXXXXX #\\\"\",\n \"\\\"#----------------------------------------------------------------------#\\\"\",\n```\n\n## Configure the VPN Clients\n\nCertificates and configuration files that users will need are placed in the `configs` directory. Make sure to secure these files since many contain private keys. All files are saved under a subdirectory named with the IP address of your new Algo VPN server.\n\n### Apple Devices\n\n**Send users their Apple Profile.** Find the corresponding mobileconfig (Apple Profile) for each user and send it to them over AirDrop or other secure means. Apple Configuration Profiles are all-in-one configuration files for iOS and macOS devices. On macOS, double-clicking a profile to install it will fully configure the VPN. On iOS, users are prompted to install the profile as soon as the AirDrop is accepted.\n\n**Turn on the VPN.** On iOS, connect to the VPN by opening Settings and clicking the toggle next to \"VPN\" near the top of the list. On macOS, connect to the VPN by opening System Preferences -> Network, finding Algo VPN in the left column and clicking \"Connect.\" On macOS, check \"Show VPN status in menu bar\" to easily connect and disconnect from the menu bar.\n\n**Managing On-Demand VPNs.** If you enabled \"On Demand\", the VPN will connect automatically whenever it is able. On iOS, you can turn off \"On Demand\" by clicking the (i) next to the entry for Algo VPN and toggling off \"Connect On Demand.\" On macOS, you can turn off \"On Demand\" by opening the Network Preferences, finding Algo VPN in the left column, and unchecking the box for \"Connect on demand.\"\n\n### Android Devices\n\nWireGuard is used to provide VPN services on Android. Install the [WireGuard VPN Client](https://play.google.com/store/apps/details?id=com.wireguard.android). Import the corresponding `wireguard/.conf` file to your device, then setup a new connection with it. See the [Android setup instructions](/docs/client-android.md) for more detailed walkthrough.\n\n### Windows 10\n\nCopy your PowerShell script `windows_{username}.ps1` to the Windows client and run the following command as Administrator to configure the VPN connection.\n```\npowershell -ExecutionPolicy ByPass -File windows_{username}.ps1 -Add\n```\n\nFor a manual installation, see the [Windows setup instructions](/docs/client-windows.md).\n\n### Linux Network Manager Clients (e.g., Ubuntu, Debian, or Fedora Desktop)\n\nNetwork Manager does not support AES-GCM. In order to support Linux Desktop clients, choose the \"compatible\" cryptography during the deploy process and use at least Network Manager 1.4.1. See [Issue #263](https://github.com/trailofbits/algo/issues/263) for more information.\n\n### Linux strongSwan Clients (e.g., OpenWRT, Ubuntu Server, etc.)\n\nInstall strongSwan, then copy the included ipsec_user.conf, ipsec_user.secrets, user.crt (user certificate), and user.key (private key) files to your client device. These will require customization based on your exact use case. These files were originally generated with a point-to-point OpenWRT-based VPN in mind.\n\n#### Ubuntu Server 18.04 example\n\n1. `sudo apt-get install strongswan strongswan-plugin-openssl`: install strongSwan\n2. `/etc/ipsec.d/certs`: copy `.crt` from `algo-master/configs//pki/certs/.crt`\n3. `/etc/ipsec.d/private`: copy `.key` from `algo-master/configs//pki/private/.key`\n4. `/etc/ipsec.d/cacerts`: copy `cacert.pem` from `algo-master/configs//pki/cacert.pem`\n5. `/etc/ipsec.secrets`: add your `user.key` to the list, e.g. ` : ECDSA .key`\n6. `/etc/ipsec.conf`: add the connection from `ipsec_user.conf` and ensure `leftcert` matches the `.crt` filename\n7. `sudo ipsec restart`: pick up config changes\n8. `sudo ipsec up `: start the ipsec tunnel\n9. `sudo ipsec down `: shutdown the ipsec tunnel\n\nOne common use case is to let your server access your local LAN without going through the VPN. Set up a passthrough connection by adding the following to `/etc/ipsec.conf`:\n\n conn lan-passthrough\n leftsubnet=192.168.1.1/24 # Replace with your LAN subnet\n rightsubnet=192.168.1.1/24 # Replac with your LAND subnet\n authby=never # No authentication necessary\n type=pass # passthrough\n auto=route # no need to ipsec up lan-passthrough\n\n### Other Devices\n\nDepending on the platform, you may need one or multiple of the following files.\n\n* cacert.pem: CA Certificate\n* user.mobileconfig: Apple Profile\n* user.p12: User Certificate and Private Key (in PKCS#12 format)\n* user.sswan: Android strongSwan Profile\n* ipsec_user.conf: strongSwan client configuration\n* ipsec_user.secrets: strongSwan client configuration\n* windows_user.ps1: Powershell script to help setup a VPN connection on Windows\n\n## Setup an SSH Tunnel\n\nIf you turned on the optional SSH tunneling role, then local user accounts will be created for each user in `config.cfg` and SSH authorized_key files for them will be in the `configs` directory (user.ssh.pem). SSH user accounts do not have shell access, cannot authenticate with a password, and only have limited tunneling options (e.g., `ssh -N` is required). This ensures that SSH users have the least access required to setup a tunnel and can perform no other actions on the Algo server.\n\nUse the example command below to start an SSH tunnel by replacing `user` and `ip` with your own. Once the tunnel is setup, you can configure a browser or other application to use 127.0.0.1:1080 as a SOCKS proxy to route traffic through the Algo server.\n\n `ssh -D 127.0.0.1:1080 -f -q -C -N user@ip -i configs/ip_user.ssh.pem`\n\n## SSH into Algo Server\n\nTo SSH into the Algo server for administrative purposes you can use the example command below by replacing `ip` with your own:\n\n `ssh root@ip -i ~/.ssh/algo.pem`\n\nIf you find yourself regularly logging into Algo then it will be useful to load your Algo ssh key automatically. Add the following snippet to the bottom of `~/.bash_profile` to add it to your shell environment permanently.\n\n `ssh-add ~/.ssh/algo > /dev/null 2>&1`\n\nNote the admin username is `ubuntu` instead of `root` on providers other than Digital Ocean.\n\n## Adding or Removing Users\n\nIf you chose the save the CA certificate during the deploy process, then Algo's own scripts can easily add and remove users from the VPN server.\n\n1. Update the `users` list in your `config.cfg`\n2. Open a terminal, `cd` to the algo directory, and activate the virtual environment with `source env/bin/activate`\n3. Run the command: `./algo update-users`\n\nAfter this process completes, the Algo VPN server will contains only the users listed in the `config.cfg` file.\n\n## Additional Documentation\n\n* Setup instructions\n - Documentation for available [Ansible roles](docs/setup-roles.md)\n - Deploy from [Fedora Workstation (26)](docs/deploy-from-fedora-workstation.md)\n - Deploy from [RedHat/CentOS 6.x](docs/deploy-from-redhat-centos6.md)\n - Deploy from [Windows](docs/deploy-from-windows.md)\n - Deploy from [Ansible](docs/deploy-from-ansible.md) directly\n* Client setup\n - Setup [Android](docs/client-android.md) clients\n - Setup [Generic/Linux](docs/client-linux.md) clients with Ansible\n* Cloud setup\n - Configure [Amazon EC2](docs/cloud-amazon-ec2.md)\n - Configure [Azure](docs/cloud-azure.md)\n - Configure [DigitalOcean](docs/cloud-do.md)\n* Advanced Deployment\n - Deploy to your own [FreeBSD](docs/deploy-to-freebsd.md) server\n - Deploy to your own [Ubuntu 18.04](docs/deploy-to-ubuntu.md) server\n - Deploy to an [unsupported cloud provider](docs/deploy-to-unsupported-cloud.md)\n* [FAQ](docs/faq.md)\n* [Troubleshooting](docs/troubleshooting.md)\n\nIf you read all the documentation and have further questions, [join the chat on Gitter](https://gitter.im/trailofbits/algo).\n\n## Endorsements\n\n> I've been ranting about the sorry state of VPN svcs for so long, probably about\n> time to give a proper talk on the subject.
