twisted.internet.ssl.DistinguishedName(dict) class documentation

Identify and describe an entity.

Distinguished names are used to provide a minimal amount of identifying information about a certificate issuer or subject. They are commonly created with one or more of the following fields:

   commonName (CN)
   organizationName (O)
   organizationalUnitName (OU)
   localityName (L)
   stateOrProvinceName (ST)
   countryName (C)
   emailAddress

A DistinguishedName should be constructed using keyword arguments whose keys can be any of the field names above (as a native string), and the values are either Unicode text which is encodable to ASCII, or bytes limited to the ASCII subset. Any fields passed to the constructor will be set as attributes, accessible using both their extended name and their shortened acronym. The attribute values will be the ASCII-encoded bytes. For example:

   >>> dn = DistinguishedName(commonName=b'www.example.com',
   ...                        C='US')
   >>> dn.C
   b'US'
   >>> dn.countryName
   b'US'
   >>> hasattr(dn, "organizationName")
   False

DistinguishedName instances can also be used as dictionaries; the keys are extended name of the fields:

   >>> dn.keys()
   ['countryName', 'commonName']
   >>> dn['countryName']
   b'US'
