letsencrypt-fast

The fastest way to test/generate/renew Let's Encrypt SSL certificates!!!

Requires root access and a live webserver to run the script at.

The script must run on the live web server.

It supports multiple domains/sites on the same server to obtain a valid SSL certificate.

IT DOES NOT stop the server from running in order to validate!

If put on cron it renews automatically 7 days before expiration.

These scripts are based on the excellent work of the people at https://zerossl.com/.

Contains two (2) bash scripts:

• install.sh that will install and create the appropriate directories
• le.sh that handles all the SSL certificate generation/renewing

The install.sh script is for an Ubuntu/Debian Linux flavour.

If you need to install zerossl for another flavour just navigate here: https://zerossl.com/installation.html

Steps to install

• wget https://raw.githubusercontent.com/davidoster/letsencrypt-fast/master/install.sh
• sudo chmod 744 ./install.sh
• ./install.sh

Usage

Arguments

• domain = just the name of the domain without the TLD (.xyz) part
• www.domain.com,domain.com = the name of the domains you want to register. They need to be comma (,) separated
• path to web domain files = the full web path of your site, e.g. /var/html/www/
• operation = valid operations are: -t for testing, -l for true generation, -r for auto renewal on 7 days before expiration

Running

For testing

./le.sh domain www.domain.com,domain.com /path/to/webdomain/files/ -t

For real generation

./le.sh domain www.domain.com,domain.com /path/to/webdomain/files/ -l

For renewal (does it 7 days before expiration automatically)

./le.sh domain www.domain.com,domain.com /path/to/webdomain/files/ -r

Auto Renewal

Run the above command in host's cron, e.g.

0 18 * * 1,3,5 root /root/software/le.sh domain domain.com,www.domain.com /path/to/domain/ -r > /dev/null 2>&1

Certificate Files

You can find the domain.crt and domain.key files under

/root/software/keys/domain.key and use these paths to your webserver,

e.g.

/root/software/keys/domain.key/domain.crt

/root/software/keys/domain.key/domain.key

Also inside this directory you can find the domain.csr file along with the file account.key for the domain in let's encrypt systems.

This is a script to help people create their FREE SSL certificate for their site(s) in a very fast and convenient way. It uses the approach from https://zerossl.com/ and installs various Perl packages in order to work. For questions or enhancements : support [at] eletter [dot] gr
