https://github.com/fin1te/safecurl/blob/master/src/fin1te/SafeCurl/SafeCurl.php#L136 checks the $url as an array for the keys user or pass, but the keys returned are hardcoded at https://github.com/fin1te/safecurl/blob/master/src/fin1te/SafeCurl/Url.php#L62 to only be originalURL cleanURL and parts, and never have user and/or pass, but that will be in cleanURL
