NameConstraintsExt Plug-in Module
Chapter 4 Certificate Extension Plug-in Modules 203
permittedSubtrees<n>.
base.generalNameValue
Specifies the general-name value for the permitted subtree you want to
include in the extension.
Permissible values: Depends on the general-name type you selected in the
permittedSubtrees<n>.base.generalNameChoice
field.
• If you selected
rfc822Name
, the value must be a valid Internet mail
address in the
local-part@domain
format; see the definition of an
rfc822Name
as defined in RFC 822
(
http://www.ietf.org/rfc/rfc0822.txt
). You may use upper
and lower case letters in the mail address; no significance is attached to
the case. For example,
testCA@example.com
.
• If you selected
directoryName
, the value must be a string form of
X.500 name, similar to the subject name in a certificate, in the RFC 2253
syntax (see
http://www.ietf.org/rfc/rfc2253.txt
). Note that
RFC 2253 replaces RFC 1779. For example,
CN=SubCA, OU=Research
Dept, O=Example Corporation, C=US
.
• If you selected
dNSName
, the value must be a valid domain name in the
preferred-name syntax as specified by RFC 1034
(
http://www.ietf.org/rfc/rfc1034.txt
). You may use upper
and lower case letters in the domain name; no significance is attached
to the case. Do not use the string “ ” for the DNS name. Also don’t use
the DNS representation for Internet mail addresses; such identities
should be encoded as
rfc822Name
. For example,
testCA.example.com
.
• If you selected
ediPartyName
, the value must be a IA5String. For
example,
Example Corporation
.
• If you selected
URL
, the value must be a non-relative universal resource
identifier (URI) following the URL syntax and encoding rules specified
in RFC 1738. That is, the name must include both a scheme (for
example,
http
) and a fully qualified domain name or IP address of the
host. For example,
http://testCA.example.com
.
