When you set Let's Encrypt up, you will:
- generate a key on your computer (among other things), which we will call
domain.key - regularly update a certificate file via Let's Encrypt (most probably using one of the
Acme Client Implementations), we will
call this file
domain.crt
The domain.key file is for your eyes only; you should keep it safe where you run taskd
and set server.key to point to it.
