The tool helps to renew letsencrypt certiicates from cron

The tool is written in go, so you will need a go compiler.

It's often shipped with Linux distribution, for example on debian you can install the golang package:

$ sudo apt-get install golang

Then to install the tool run the following command:

$ export GOPATH="$HOME/gocode";
$ go get github.com/Ajnasz/letsencrypt-expiring-certs

This will download and also compile the code:

In the $HOME/gocode/bin/ folder you will find the binary.

In the gocode/src/github.com/Ajnasz/letsencrypt-expiring-certs/ folder you will find the source code.

In the folder of the source code you can build tool again by using the go build command.

If you use other OS then Linux or other distribution, read the documenatition: https://golang.org/doc/install

List domains with expired certificates

$ ./letsencrypt-expiring-certs -expire="`date`"

List domains of certificates which will expire in 2 weeks

$ ./letsencrypt-expiring-certs -expire="`date --date='2 weeks'`"

List domains of certificates which will expire at 03/05/2016 11:28

$ ./letsencrypt-expiring-certs -expire="`date --date '03/05/2016 11:28'`"

Use the -certs-path option to change the default path of certificates (/etc/letsencrypt/live)

Use the -pem-name if the nem of your pem files is different then the default (fullchain.pem)

You can see an example cron script in the scripts folder, see the scritps/cron.sh Make sure every path is correct in the script.

You can download prebuild binary from the following link: http://bit.ly/1U1JqfO sha1: http://bit.ly/1mkl9V9

Download the file, check if the file not damaged:

$ wget http://bit.ly/1U1JqfO
$ wget http://bit.ly/1mkl9V9
$ sha1sum -c sha1.sum

Unzip and make the file executable:

$ gunzip letsencrypt-expiring-certs.2.0.2.gz
$ chmod +x letsencrypt-expiring-certs.2.0.2
$ mv letsencrypt-expiring-certs.2.0.2 letsencrypt-expiring-certs
