+.Sh DESCRIPTION
+Using the information access extensions, certificates and certificate
+revocation lists can point to auxiliary information and services
+available online, for example online validation services or CA
+policy data.
+.Pp
+.Fn ACCESS_DESCRIPTION_new
+allocates and initializes an empty
+.Vt ACCESS_DESCRIPTION
+object, representing an ASN.1 AccessDescription structure
+defined in RFC 5280 section 4.2.2.1.
+It can hold a pointer to a
+.Vt GENERAL_NAME
+object documented in
+.Xr GENERAL_NAME_new 3
+and an access method identifier.
+.Fn ACCESS_DESCRIPTION_free
+frees
+.Fa ad .
+.Pp
+The access method identifier is somewhat misnamed; it identifies
+the type and format of the information provided.
+How to access that information is often obvious from the
+.Vt GENERAL_NAME
+which may for example include a uniform resource identifier.
+.Pp
+Four standard access method identifiers are defined in RFC 5280:
+.Bl -bullet
+.It
+.Qq id-ad-caIssuers
+can occur in the authority information access extension of certificates
+and certificate revocation lists and provides access to certificates
+issued to the CA that issued the certificate, or provides access
+to certificates used for signing the CRL, in order to help constructing
+a certification path.
+.It
+.Qq id-ad-ocsp
+can occur in the authority information access extension of certificates
+and provides access to revocation information via the Online
+Certificate Status Protocol (OCSP) defined in RFC 6960.
+.It
+.Qq id-ad-caRepository
+can occur in the subject information access extension of CA
+certificates and provides access to an online repository of
+certificates issued by the CA.
+.It
+.Qq id-ad-timeStamping
+can occur in the subject information access extension of end entity
+certificates and indicates that the subject offers timestamping
+services using the Time Stamp Protocol defined in RFC 3161.
+.El
+.Pp
+.Fn AUTHORITY_INFO_ACCESS_new
+allocates and initializes an empty
+.Vt AUTHORITY_INFO_ACCESS
+object, which is a
+.Vt STACK_OF(ACCESS_DESCRIPTION)
+and represents an ASN.1 AuthorityInfoAccessSyntax structure
+defined in RFC 5280 section 4.2.2.1.
+If can be used for the authority information access extension of
+certificates and certificate revocation lists and for the subject
+information access extension of certificates.
+.Fn AUTHORITY_INFO_ACCESS_free

+.Fa aia .
+.Sh RETURN VALUE
+.Fn ACCESS_DESCRIPTION_new
+and
+.Fn AUTHORITY_INFO_ACCESS_new
+return the new
+.Vt ACCESS_DESCRIPTION
+or
+.Vt AUTHORITY_INFO_ACCESS
+object, respectively, or
+.Dv NULL
+if an error occurs.
