internal package Foswiki::Configure::Checkers::Certificate::KeyChecker This checker validates files that contain private key files such as for the S/MIME signatures and for the Tasks framework.
It must be subclassed for the various certificate types, as the requirements are slightly different.
ObjectMethod check( $keys, $password, $reporter ) $keys - configure value object
$password - Optional password key name for this file
A lot of checking is done here to prevent mystery errors at runtime.
