OpenSSL::X509::Name

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']]

Constants

COMPAT

A flag for to_s.

Breaks the name returned into multiple lines if longer than 80 characters.

DEFAULT_OBJECT_TYPE

The default object type for name entries.

MULTILINE

A flag for to_s.

Returns a multiline format.

OBJECT_TYPE_TEMPLATE

The default object type template for name entries.

ONELINE

A flag for to_s.

Returns a more readable format than RFC2253.

RFC2253

A flag for to_s.

Returns an RFC2253 format name.

X509::Name.new => name click to toggle source
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

Public Instance Methods

<=>(p1) click to toggle source
Alias for: cmp
add_entry(oid, value [, type], loc: -1, set: 0) => self click to toggle source

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.
