Ipinator extension key code#

If the keyid option is present an attempt is made to copy the subject key identifier from the parent certificate.

keyid and issuer: both can take the optional value 'always'. The authority key identifier extension permits two options. The use of the hex string is strongly discouraged.Įxample: subjectKeyIdentifier=hash Authority Key Identifier. Either the word hash which will automatically follow the guidelines in RFC3280 or a hex string giving the extension value to include. This is really a string extension and can take two possible values.

In particular the following PKIX, NS and MS values are meaningful: Value Meaning While any OID can be used only certain values make sense. These can either be object short names or the dotted numerical form of OIDs. This extensions consists of a list of usages indicating purposes for which the certificate public key can be used for, KeyUsage=critical, ke圜ertSign Extended Key Usage. The supported names are: digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment, keyAgreement, ke圜ertSign, cRLSign, encipherOnly and decipherOnly.Įxamples: keyUsage=digitalSignature, nonRepudiation Key usage is a multi valued extension consisting of a list of names of the permitted key usages. So if you have a CA with a pathlen of zero it can only be used to sign end user certificates and not further CAs. The pathlen parameter indicates the maximum number of CAs that can appear below this one in a chain.

Some software may require the inclusion of basicConstraints with CA set to FALSE for end entity certificates. An end user certificate must either set CA to FALSE or exclude the extension entirely. If CA is TRUE then an optional pathlen name followed by a nonnegative value can be included.īasicConstraints=critical,CA:TRUE, pathlen:0Ī CA certificate must include the basicConstraints value with the CA field set to TRUE.

The first (mandatory) name is CA followed by TRUE or FALSE. This is a multi valued extension which indicates whether a certificate is a CA certificate. The following sections describe each supported extension in detail. If an extension type is unsupported then the arbitrary extension syntax must be used, see the ARBITRARY EXTENSIONS section for more details. The correct syntax to use is defined by the extension code itself: check out the certificate policies extension for an example. The syntax of raw extensions is governed by the extension code: it can for example contain data in multiple sections.

The long form allows the values to be placed in a separate section: forms are equivalent. The short form is a list of names and values: basicConstraints=critical,CA:true,pathlen:1 Multi-valued extensions have a short form and a long form. String extensions simply have a string which contains either the value itself or how it is obtained.įor example: nsComment='This is a Comment' There are four main types of extension: string extensions, multi-valued extensions, raw and arbitrary extensions. The format of extension_options depends on the value of extension_name. If critical is present then the extension will be critical. Each line of the extension section takes the form: extension_name= extension_options Typically the application will contain an option to point to an extension section. Several of the OpenSSL utilities can add extensions to a certificate or certificate request based on the contents of a configuration file.
