Hi RG,
With deSEC, “Let’s Encrypt integration” means that our API is integrated into several certificate management tools (such as acme.sh, or lego). However, we do not “integrate” so far as to generate your certificate for you.
(We also don’t want to do that; we think we should not meddle with your certificate stuff. One disadvantage of that would be, for example, that you would have to get a new certificate from deSEC once it expires. With the other tools, you can instead have a fully automated renewal, so that’s better!)
To check out the tools you can use to automate certificate generation (and renewal) with deSEC, please take a look at or list of Tools implementing deSEC.
Stay secure,
Peter
