Managing Let's Encrypt Settings

Plesk Let's Encrypt extension behavior is governed by a number of settings, for example:

  • How far in advance of the expiration date Let's Encrypt Certificates are renewed.
  • Whether the requests to the ACME server are recorded in the Plesk log or not.
  • The size of the RSA private key, and so on.

You can change these settings by specifying custom values in the [ext-letsencrypt] section of the panel.ini configuration file. For example, to have Let's Encrypt renew certificates 45 days in advance and to change the size of the RSA private key to 4096 bits, add the following section to the panel.ini file:

[ext-letsencrypt]
renew-before-expiration = 45
rsa-key-size = 4096
