Overview

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']]

Constructor Details

X509::Name.newName X509::Name.new(der) ⇒ Name X509::Name.new(distinguished_name) ⇒ Name X509::Name.new(distinguished_name, template) ⇒ Name

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

Instance Method Details

#cmp(other) ⇒ 1 #<=>(other) ⇒ 1
Also known as: #cmp

Compares this Name with other and returns 0 if they are the same and -1 or +1 if they are greater or less than each other respectively. Returns nil if they are not comparable (i.e. different types).

#add_entry(oid, value [, type], loc: -1, set: 0) ⇒ self

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.
