Requests_SSL::verify_reference_name()public staticWP 1.0

Verify that a reference name is valid

Verifies a dNSName for HTTPS usage, (almost) as per Firefox's rules:

  • Wildcards can only occur in a name with more than 3 components
  • Wildcards can only occur as the last character in the first component
  • Wildcards may be preceded by additional characters

We modify these rules to be a bit stricter and only allow the wildcard character to be the full first component; that is, with the exclusion of the third rule.
