 You can ignore certain advisories while checking by specifying a list
 of regular expressions[^1] to match their URLs by using the `ignorepattern`
 option.

 the sub strings **white** or **red**.

 If a provider hosts one or more advisories with a TLP level of AMBER or RED, then these advisories must be access protected.
 To check these advisories, authorization can be given via custom headers or certificates.

 #### Forwarding

 The downloader is able to forward downloaded advisories and their checksums,
 OpenPGP signatures and validation results to an HTTP endpoint.  
 The details of the implemented API are described [here](https://github.com/mfd2007/csaf_upload_interface).
