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(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

<=>(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.
