DESCRIPTION
Using the CRL distribution point extension, a certificate can specify where to obtain certificate revocation lists that might later revoke it.
DIST_POINT_new()
allocates and initializes an empty 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.
DIST_POINT_free()
frees dp.
CRL_DIST_POINTS_new()
allocates and initializes an empty CRL_DIST_POINTS
object, which is a 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
X509 and in X509_CRL objects.
CRL_DIST_POINTS_free()
frees dps.
DIST_POINT_NAME_new()
allocates and initializes an empty DIST_POINT_NAME
object, representing an ASN.1 DistributionPointName
structure defined in RFC 5280 section 4.2.1.13. It is used by the
DIST_POINT and
ISSUING_DIST_POINT objects and can hold multiple
names, each representing a different way to obtain the same CRL.
DIST_POINT_NAME_free()
frees name.
ISSUING_DIST_POINT_new()
allocates and initializes an empty 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.
ISSUING_DIST_POINT_free()
frees dp.
RETURN VALUES
DIST_POINT_new(),
CRL_DIST_POINTS_new(),
DIST_POINT_NAME_new(), and
ISSUING_DIST_POINT_new() return the new
DIST_POINT, CRL_DIST_POINTS,
DIST_POINT_NAME, or
ISSUING_DIST_POINT object, respectively, or
NULL if an error occurs.
