.name_from_subject(subject) ⇒ String

This method is part of a private API. You should avoid using this method if possible, as it may be removed or be changed in the future.

name_from_subject extracts the common name attribute from the subject of an x.509 certificate certificate

Parameters:

  • subject (OpenSSL::X509::Name) —

    The full subject (distinguished name) of the x.509 certificate.

Returns:

  • (String) —

    the name (CN) extracted from the subject.
