Let's Encrypt
Previous Topic  Next Topic 

Let's Encrypt is a free, automated, and open certificate authority created by the Electronic Frontier Foundation. While Certbot, the recommended Let's Encrypt client, is not fully supported in Windows, you may use other compatible clients. This guide will detail instructions using the ACMESharp shell client.


Follow the steps in the ACMESharp guide to install ACMESharp and obtain a certificate. For step 5, we recommend validating your domain via DNS (Method #3).


Once your domain has been marked as valid, you can retrieve the certificate by following the instructions in the ACMESharp guide.


Combine the .key and .cert files you created in step 2. To do this, use a text editor like Notepad and paste the contents of both files into a new file named Fusion.pem (not Fusion.pem.txt)


IMPORTANT: The format for Fusion.pem must be:


-----BEGIN CERTIFICATE-----

*certificate in here*

-----END CERTIFICATE-----

-----BEGIN RSA PRIVATE KEY-----

*RSA key in here*

-----END RSA PRIVATE KEY-----
