TElAuthorityInformationAccessExtension class

Properties     Methods     Declared in     

TElAuthorityInformationAccessExtension is a descendant of TElCustomExtension class.


    The authority information access extension indicates how to access CA information for the issuer of the certificate.

    The following paragraph is taken from RFC 2459 (Housley, et. al.), part

    «Each entry ... describes the format and location of additional information about the CA who issued the certificate in which this extension appears. The type and format of the information is specified by the accessMethod field; the accessLocation field specifies the location of the information. The retrieval mechanism may be implied by the accessMethod or specified by accessLocation.

    This profile defines one OID for accessMethod. The id-ad-caIssuers OID is used when the additional information lists CAs that have issued certificates superior to the CA that issued the certificate containing this extension. The referenced CA Issuers description is intended to aid certificate users in the selection of a certification path that terminates at a point trusted by the certificate user. »

    This extension may be included in subject or CA certificates, and it MUST be non-critical.
