The X509_LOOKUP_METHOD type is a structure used for the implementation of new X509_LOOKUP types. It provides a set of functions used by OpenSSL for the implementation of various X509 and X509_CRL lookup capabilities. One instance of an X509_LOOKUP_METHOD can be associated to many instantiations of an X509_LOOKUP structure.
X509_LOOKUP_meth_new()
creates a new X509_LOOKUP_METHOD structure. It should
be given a human-readable string containing a brief description of the lookup
method.
X509_LOOKUP_meth_free()
destroys a X509_LOOKUP_METHOD structure.
X509_LOOKUP_get_new_item()
and X509_LOOKUP_set_new_item()
get and set the
function that is called when an X509_LOOKUP object is created with
X509_LOOKUP_new(). If an X509_LOOKUP_METHOD requires any per-X509_LOOKUP
specific data, the supplied new_item function should allocate this data and
invoke X509_LOOKUP_set_method_data().
X509_LOOKUP_get_free()
and X509_LOOKUP_set_free()
get and set the function
that is used to free any method data that was allocated and set from within
new_item function.
X509_LOOKUP_meth_get_init()
and X509_LOOKUP_meth_set_init()
get and set the
function that is used to initialize the method data that was set with
X509_LOOKUP_set_method_data()
as part of the new_item routine.
X509_LOOKUP_meth_get_shutdown()
and X509_LOOKUP_meth_set_shutdown()
get and set
the function that is used to shut down the method data whose state was
previously initialized in the init function.
X509_LOOKUP_meth_get_ctrl()
and X509_LOOKUP_meth_set_ctrl()
get and set a
function to be used to handle arbitrary control commands issued by
X509_LOOKUP_ctrl(). The control function is given the X509_LOOKUP
ctx, along with the arguments passed by X509_LOOKUP_ctrl. cmd is
an arbitrary integer that defines some operation. argc is a pointer
to an array of characters. argl is an integer. ret, if set,
points to a location where any return data should be written to. How
argc and argl are used depends entirely on the control function.
X509_LOOKUP_set_get_by_subject(), X509_LOOKUP_set_get_by_issuer_serial(),
X509_LOOKUP_set_get_by_fingerprint(), X509_LOOKUP_set_get_by_alias()
set
the functions used to retrieve an X509 or X509_CRL object by the object's
subject, issuer, fingerprint, and alias respectively. These functions are given
the X509_LOOKUP context, the type of the X509_OBJECT being requested, parameters
related to the lookup, and an X509_OBJECT that will receive the requested
object.
Implementations should use either X509_OBJECT_set1_X509()
or
X509_OBJECT_set1_X509_CRL()
to set the result. Any method data that was
created as a result of the new_item function set by
X509_LOOKUP_meth_set_new_item()
can be accessed with
X509_LOOKUP_get_method_data(). The X509_STORE object that owns the
X509_LOOKUP may be accessed with X509_LOOKUP_get_store(). Successful lookups
should return 1, and unsuccessful lookups should return 0.
X509_LOOKUP_get_get_by_subject(), X509_LOOKUP_get_get_by_issuer_serial(),
X509_LOOKUP_get_get_by_fingerprint(), X509_LOOKUP_get_get_by_alias()
retrieve
the function set by the corresponding setter.
The X509_LOOKUP_meth_set functions return 1 on success or 0 on error.
The X509_LOOKUP_meth_get functions return the corresponding function pointers.
X509_STORE_new(3), SSL_CTX_set_cert_store(3)
