5.2.1 General Purpose Extension Structure

The following extension is the genera purpose structure that allows data to be specified for most supported extensions.

    typedef struct NPKI_Extension
    {
         nuint32      flags;
         nuint32      length;     /* length of value */
         nuint8       *value;
    }NPKI_Extension;
    
    

flags

Specifies how the extension is encoded in the certificate. flag is composed of both general purpose flags combined with any extension specific flags if necessary. See General Purpose Extension Flags.

length

Specifies the number of bytes which follow in value. If the extension is not to be encoded in the certificate, flags should be set to PKI_EXTENSION_DONT_INCLUDE, length should be set to 0 and value should be NULL.

value

Points to a byte-array of data.
