CertificateExtensionAuthorityKeyIdentifier

Added in version 4.3.91.

class CertificateExtensionAuthorityKeyIdentifier(**properties: Any)

Superclasses: CertificateExtension, Object

A certificate extension that contains the authority key identifier (SKI).

This extension may expose the authority key identifier directly, which should match the subject key identifier of the parent certificate.

It may also expose a combination of issuer name and serial number of the used certificate instead. This is rare however.
