X509_EXTENSION_set_object()
sets the extension type of ex to obj. The
obj pointer is duplicated internally so obj should be freed up after use.
X509_EXTENSION_set_critical()
sets the criticality of ex to crit. If
crit is zero the extension in non-critical otherwise it is critical.
X509_EXTENSION_set_data()
sets the data in extension ex to data. The
data pointer is duplicated internally.
X509_EXTENSION_create_by_NID()
creates an extension of type nid,
criticality crit using data data. The created extension is returned and
written to *ex reusing or allocating a new extension if necessary so *ex
should either be NULL or a valid X509_EXTENSION structure it must
not be an uninitialised pointer.
X509_EXTENSION_create_by_OBJ()
is identical to X509_EXTENSION_create_by_NID()
except it creates and extension using obj instead of a NID.
X509_EXTENSION_get_object()
returns the extension type of ex as an
ASN1_OBJECT pointer. The returned pointer is an internal value which must
not be freed up.
X509_EXTENSION_get_critical()
returns the criticality of extension ex it
returns 1 for critical and 0 for non-critical.
X509_EXTENSION_get_data()
returns the data of extension ex. The returned
pointer is an internal value which must not be freed up.
These functions manipulate the contents of an extension directly. Most
applications will want to parse or encode and add an extension: they should
use the extension encode and decode functions instead such as
X509_add1_ext_i2d()
and X509_get_ext_d2i().
The data associated with an extension is the extension encoding in an ASN1_OCTET_STRING structure.
X509_EXTENSION_set_object()
X509_EXTENSION_set_critical()
and
X509_EXTENSION_set_data()
return 1 for success and 0 for failure.
X509_EXTENSION_create_by_NID()
and X509_EXTENSION_create_by_OBJ()
return
an X509_EXTENSION pointer or NULL if an error occurs.
X509_EXTENSION_get_object()
returns an ASN1_OBJECT pointer.
X509_EXTENSION_get_critical()
returns 0 for non-critical and 1 for
critical.
X509_EXTENSION_get_data()
returns an ASN1_OCTET_STRING pointer.
