Remarks

A certificate extension consists of an object identifier (OID), a Boolean value that identifies whether the extension is critical, and a byte array that contains the extension value. The criticality indicates whether an application that uses a certificate can ignore the extension type and value. If an extension is identified as critical but the application does not recognize the extension type, the application should reject the certificate.
