#### General
This is a work in progress. Please do *NOT* run this on a production server and please report any bugs you find!
## Installation

#### Installation
lego supports both binary installs and install from source.

To get the binary just download the latest release for your OS/Arch from [the release page](https://github.com/xenolf/lego/releases)
and put the binary somewhere convenient. lego does not assume anything about the location you run it from.

To install from source, just run
```
To install from source, just run:

```bash
go get -u github.com/xenolf/lego
```

To build lego inside a Docker container, just run
```

```bash
docker build -t lego .
```

The container is, by default, built from `master`.
This can be overridden by supplying a build argument containing a git SHA or reference.
That will build lego from the current source, if you want to build a different
version, you can checkout the desired branch/tag/commit, and re-running the
above mentioned command.

If you want to tag the binary with the designated release, you can do so by
passing the version identifier as a [`--build-arg`](https://docs.docker.com/engine/reference/commandline/build/#set-build-time-variables---build-arg)

```bash
docker build --build-arg LEGO_VERSION=tags/v0.5.0 -t lego .
docker build --build-arg LEGO_VERSION=v1.0.0 -t lego .
```

##### From the package manager
Otherwise the release will be tagged with the `dev` version identifier.

### From the package manager

- [ArchLinux (AUR)](https://aur.archlinux.org/packages/lego-git):

#### Features

## Features

- Register with CA
- Obtain certificates, both from scratch or with an existing CSR

When using the standard `--path` option, all certificates and account configurations are saved to a folder *.lego* in the current working directory.

#### Sudo
The CLI does not require root permissions but needs to bind to port 80 and 443 for certain challenges.
To run the CLI without sudo, you have four options:

- Use setcap 'cap_net_bind_service=+ep' /path/to/program
- Pass the `--http` or/and the `--tls` option and specify a custom port to bind to. In this case you have to forward port 80/443 to these custom ports (see [Port Usage](#port-usage)).
- Pass the `--webroot` option and specify the path to your webroot folder. In this case the challenge will be written in a file in `.well-known/acme-challenge/` inside your webroot.
- Pass the `--dns` option and specify a DNS provider.

#### Port Usage
By default lego assumes it is able to bind to ports 80 and 443 to solve challenges.
If this is not possible in your environment, you can use the `--http` and `--tls` options to instruct
lego to listen on that interface:port for any incoming challenges.

If you are using this option, make sure you proxy all of the following traffic to these ports.

HTTP Port:
- All plaintext HTTP requests to port 80 which begin with a request path of `/.well-known/acme-challenge/` for the HTTP challenge.

TLS Port:
- All TLS handshakes on port 443 for the TLS-SNI challenge.

This traffic redirection is only needed as long as lego solves challenges. As soon as you have received your certificates you can deactivate the forwarding.

### CLI Example
Assumes the `lego` binary has permission to bind to ports 80 and 443. You can get a pre-built binary from the [releases](https://github.com/xenolf/lego/releases) page.
If your environment does not allow you to bind to these ports, please read [Port Usage](#port-usage).
Obtain a certificate:
```bash
$ lego --email="foo@bar.com" --domains="example.com" run
lego --email="foo@bar.com" --domains="example.com" run
```
(Find your certificate in the `.lego` folder of current working directory.)
To renew the certificate:
```bash
$ lego --email="foo@bar.com" --domains="example.com" renew
lego --email="foo@bar.com" --domains="example.com" renew
```
To renew the certificate only if it's older than 30 days
```bash
$ lego --email="foo@bar.com" --domains="example.com" renew --days 30
lego --email="foo@bar.com" --domains="example.com" renew --days 30
```
Obtain a certificate using the DNS challenge and AWS Route 53:
```bash
$ AWS_REGION=us-east-1 AWS_ACCESS_KEY_ID=my_id AWS_SECRET_ACCESS_KEY=my_key lego --email="foo@bar.com" --domains="example.com" --dns="route53" run
AWS_REGION=us-east-1 AWS_ACCESS_KEY_ID=my_id AWS_SECRET_ACCESS_KEY=my_key lego --email="foo@bar.com" --domains="example.com" --dns="route53" run
```
Note that `--dns=foo` implies `--exclude=http-01`. lego will not attempt other challenges if you've told it to use DNS instead.
Obtain a certificate given a certificate signing request (CSR) generated by something else:
```bash
$ lego --email="foo@bar.com" --csr=/path/to/csr.pem run
lego --email="foo@bar.com" --csr=/path/to/csr.pem run
```
(lego will infer the domains to be validated based on the contents of the CSR, so make sure the CSR's Common Name and optional SubjectAltNames are set correctly.)
lego defaults to communicating with the production Let's Encrypt ACME server. If you'd like to test something without issuing real certificates, consider using the staging endpoint instead:
```bash
$ lego --server=https://acme-staging.api.letsencrypt.org/directory …
lego --server=https://acme-staging.api.letsencrypt.org/directory …
```

## ACME v1
lego introduced support for ACME v2 in [v1.0.0](https://github.com/xenolf/lego/releases/tag/v1.0.0), if you still need to utilize ACME v1, you can do so by using the [v0.5.0](https://github.com/xenolf/lego/releases/tag/v0.5.0) version.
