Let's Encrypt client and library in go!

This is a work in progress. Please do NOT run this on a production server.

####Current Status The code in this repository is currently quite raw. You are currently able to register an account with the ACME server as well as request certificates through the CLI.

Please keep in mind that CLI switches and APIs are still subject to change.

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

####Sudo I tried to not need sudo apart from challenges where binding to a privileged port is necessary. To run the CLI without sudo, you have two options:

• Use setcap 'cap_net_bind_service=+ep' /path/to/program
• Pass the --port option and specify a custom port to bind to. In this case you have to forward port 443 to this custom port.
