An X.509 name represents a hostname, email address or other entity associated with a public key.
You can create a Name
by parsing a distinguished name String
or by supplying the distinguished name as an Array
.
name = OpenSSL::X509::Name.parse 'CN=nobody/DC=example' name = OpenSSL::X509::Name.new [['CN', 'nobody'], ['DC', 'example']]
The default object type for name entries.
The default object type template for name entries.

Creates a new Name
.
A name may be created from a DER encoded string der, an Array
representing a distinguished_name or a distinguished_name along with a template.
name = OpenSSL::X509::Name.new [['CN', 'nobody'], ['DC', 'example']] name = OpenSSL::X509::Name.new name.to_der
See add_entry
for a description of the distinguished_name Array’s contents

Adds a new entry with the given oid and value to this name. The oid is an object identifier defined in ASN.1. Some common OIDs are:
- C
-
Country
Name
- CN
-
Common
Name
- DC
-
Domain Component
- O
-
Organization
Name
- OU
-
Organizational Unit
Name
- ST
-
State or Province
Name
The optional keyword parameters loc and set specify where to insert the new attribute. Refer to the manpage of X509_NAME_add_entry(3) for details. loc defaults to -1 and set defaults to 0. This appends a single-valued RDN to the end.
