Post Processing Script / Binary

Cert Warden can execute a script or binary after each certificate renewal. To use this option, just specify the script or binary under the certificate's Post Processing options, along with any needed environment variables.

Cert Warden automatically deduces if the specified file is a binary or script.

In addition to defining static environment variables, certain dynamic values are available. The placeholders below will be replaced with the actual value before setting the environmnet variable.

  • {{PRIVATE_KEY_NAME}} - The name of the private key that corresponds to the new certificate.
  • {{PRIVATE_KEY_PEM}} - The actual PEM data of the private key.
  • {{CERTIFICATE_NAME}} - The name of the certificate.
  • {{CERTIFICATE_PEM}} - The actual PEM data of the newly issued certificate.
  • {{CERTIFICATE_COMMON_NAME}} - The CN of the newly issued certificate.
