Hooks

An executable can be called after completion with information about failure(s).

Hook arguments:

/path/to/hook EXIT_CODE [DOMAIN_LIST]

• EXIT_CODE is the exit status of the validator (0 or 1)
• DOMAIN_LIST a list of invalid domains, grouped by certificate
  • Domains are joined by ,
  • Groups are joined by ;
  • Example: abc.co,www.abc.co;xyz.co,www.xyz.co
    • Two certs: abc.co & xyz.co, both with alternate domain name: www.

Success example:

/path/to/hook 0

Failure example:

/path/to/hook 1 abc.co,www.abc.co;xyz.co,www.xyz.co
