METHODS

new

Initiates the object.

    - acl :: The ACL hash to use.
        - Default :: {
                        'undef' => {
                                ip_auth       => 0,

                        },
                }

check

    - apikey :: The API key to check for. If not specified it is set to 'undef'
            and if none match, the it is set to 'nonexistent'.
        - Default :: 'undef'

    - slugs :: An array of slugs to check again. All must match. If undef or none
            are specified, a value of 'undef' is added.
        - Default :: ['undef']

    - ip :: An IP to check for.
        - Default :: undef

ACL HASH

The ACL hash is a hash of hashes. The keys for primary hash are API keys. The keys for the subhashes are as below.

Slugs should be though of a freeform text field for access check. Function name or whatever.

    - ip_auth :: Use IP for authing. If false, the IP will not be checked.
        - Default :: 0

    - slug_auth :; Use the slug for authing. If false it won't be checked.
        - Default :: 0

    - require_ip :: Require a value for IP to be specified.
        - Default :: 0

    - require_slug :: Require a value for slug to be specified.
        - Default :: 0

    - final :: The return value for if none of the auth checks are denied.
         - Default for 'undef'/'nonexistent' apikeys:: 0
         - Default for other apikeys:: 1

    - slugs :; Slugs that are allowed for access.
        - Default :: []

    - slugs_regex :: Regexps to check slug values against.
        - Default :: []

    - allow_subnets :: Allowed subnets for remote IPs. This is a array of CIDRs.
        - Default :: []

    - deny_subnets :: Denied subnets for remote IPs. This is a array of CIDRs.
        - Default :: []

There are two special ones for the ACL hash. Those are 'undef' and 'nonexistent' and they should not be used as API keys. These are for in the instances that the apikey for the checkis undef or if specified and does not exist 'nonexistent' is used.

By default they are as below.

                {
                        'undef' => {
                                ip_auth       => 0,
                                slug_auth     => 0,
                                require_ip    => 0,
                                require_slug  => 0,
                                final         => 0,
                                slugs         => [],
                                slugs_regex   => [],
                                allow_subnets => [],
                                deny_subnets  => [],
                        },
                        'nonexistent' => {
                                ip_auth       => 0,
                                slug_auth     => 0,
                                require_ip    => 0,
                                require_slug  => 0,
                                final         => 0,
                                slugs         => [],
                                slugs_regex   => [],
                                allow_subnets => [],
                                deny_subnets  => [],
                        },
                }
