+.Sh DESCRIPTION
+Using the CRL distribution point extension, a certificate can specify
+where to obtain certificate revocation lists that might later revoke it.
+.Pp
+.Fn DIST_POINT_new
+allocates and initializes an empty
+.Vt DIST_POINT
+object, representing an ASN.1 DistributionPoint structure
+defined in RFC 5280 section 4.2.1.13.
+It can hold issuer names, distribution point names, and reason flags.
+.Fn DIST_POINT_free
+frees
+.Fa dp .
+.Pp
+.Fn CRL_DIST_POINTS_new
+allocates and initializes an empty
+.Vt CRL_DIST_POINTS
+object, which is a
+.Vt STACK_OF(DIST_POINT)
+and represents the ASN.1 CRLDistributionPoints structure
+defined in RFC 5280 section 4.2.1.13.
+It can be used as an extension in
+.Vt X509
+and in
+.Vt X509_CRL
+objects.
+.Fn CRL_DIST_POINTS_free
+frees
+.Fa dps .
+.Pp
+.Fn DIST_POINT_NAME_new
+allocates and initializes an empty
+.Vt DIST_POINT_NAME
+object, representing an ASN.1 DistributionPointName structure
+defined in RFC 5280 section 4.2.1.13.
+It is used by the
+.Vt DIST_POINT
+and
+.Vt ISSUING_DIST_POINT
+objects and can hold multiple names, each representing a different
+way to obtain the same CRL.
+.Fn DIST_POINT_NAME_free
+frees
+.Fa name .
+.Pp
+.Fn ISSUING_DIST_POINT_new
+allocates and initializes an empty
+.Vt ISSUING_DIST_POINT
+object, representing an ASN.1 IssuingDistributionPoint structure
+defined in RFC 5280 section 5.2.5.
+Using this extension, a CRL can specify which distribution point
+it was issued from and which kinds of certificates and revocation
+reasons it covers.
+.Fn ISSUING_DIST_POINT_free
+frees
+.Fa dp .
+.Sh RETURN VALUES
+.Fn DIST_POINT_new ,

+.Vt DIST_POINT ,

+.Vt DIST_POINT_NAME ,
+or
+.Vt ISSUING_DIST_POINT
+object, respectively, or
