DESCRIPTION
These functions decode and encode X.509 extensions that communicate where to retrieve additional information online. For details about the semantics, examples, caveats, and bugs, see ASN1_item_d2i(3).d2i_DIST_POINT()
and
i2d_DIST_POINT()
decode and encode an ASN.1 DistributionPoint structure
defined in RFC 5280 section 4.2.1.13.
d2i_CRL_DIST_POINTS()
and
i2d_CRL_DIST_POINTS()
decode and encode an ASN.1 CRLDistributionPoints
structure defined in RFC 5280 section 4.2.1.13.
d2i_DIST_POINT_NAME()
and
i2d_DIST_POINT_NAME()
decode and encode an ASN.1 DistributionPointName
structure defined in RFC 5280 section 4.2.1.13.
d2i_ISSUING_DIST_POINT()
and
i2d_ISSUING_DIST_POINT()
decode and encode an ASN.1 IssuingDistributionPoint
structure defined in RFC 5280 section 5.2.5.
d2i_ACCESS_DESCRIPTION()
and
i2d_ACCESS_DESCRIPTION()
decode and encode an ASN.1 AccessDescription structure
defined in RFC 5280 section 4.2.2.1.
d2i_AUTHORITY_INFO_ACCESS()
and
i2d_AUTHORITY_INFO_ACCESS()
decode and encode an ASN.1 AuthorityInfoAccessSyntax
structure defined in RFC 5280 section 4.2.2.1.
RETURN VALUES
d2i_DIST_POINT(),
d2i_CRL_DIST_POINTS(),
d2i_DIST_POINT_NAME(),
d2i_ISSUING_DIST_POINT(),
d2i_ACCESS_DESCRIPTION(), and
d2i_AUTHORITY_INFO_ACCESS() return an object of the
respective type or NULL if an error occurs.
i2d_DIST_POINT(),
i2d_CRL_DIST_POINTS(),
i2d_DIST_POINT_NAME(),
i2d_ISSUING_DIST_POINT(),
i2d_ACCESS_DESCRIPTION(), and
i2d_AUTHORITY_INFO_ACCESS() return the number of
bytes successfully encoded or a negative value if an error occurs.
