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 \&\fBX509_LOOKUP\fR structure. .PP \&\fBX509_LOOKUP_meth_new()\fR creates a new \fBX509_LOOKUP_METHOD\fR structure. It should be given a human-readable string containing a brief description of the lookup method. .PP \&\fBX509_LOOKUP_meth_free()\fR destroys a \fBX509_LOOKUP_METHOD\fR structure. .PP \&\fBX509_LOOKUP_get_new_item()\fR and \fBX509_LOOKUP_set_new_item()\fR get and set the function that is called when an \fBX509_LOOKUP\fR object is created with \&\fBX509_LOOKUP_new()\fR. If an X509_LOOKUP_METHOD requires any per\-X509_LOOKUP specific data, the supplied new_item function should allocate this data and invoke \fBX509_LOOKUP_set_method_data\fR\|(3). .PP \&\fBX509_LOOKUP_get_free()\fR and \fBX509_LOOKUP_set_free()\fR get and set the function that is used to free any method data that was allocated and set from within new_item function. .PP \&\fBX509_LOOKUP_meth_get_init()\fR and \fBX509_LOOKUP_meth_set_init()\fR get and set the function that is used to initialize the method data that was set with \&\fBX509_LOOKUP_set_method_data\fR\|(3) as part of the new_item routine. .PP \&\fBX509_LOOKUP_meth_get_shutdown()\fR and \fBX509_LOOKUP_meth_set_shutdown()\fR get and set the function that is used to shut down the method data whose state was previously initialized in the init function. .PP \&\fBX509_LOOKUP_meth_get_ctrl()\fR and \fBX509_LOOKUP_meth_set_ctrl()\fR get and set a function to be used to handle arbitrary control commands issued by \&\fBX509_LOOKUP_ctrl()\fR. The control function is given the X509_LOOKUP \&\fBctx\fR, along with the arguments passed by X509_LOOKUP_ctrl. \fBcmd\fR is an arbitrary integer that defines some operation. \fBargc\fR is a pointer to an array of characters. \fBargl\fR is an integer. \fBret\fR, if set, points to a location where any return data should be written to. How \&\fBargc\fR and \fBargl\fR are used depends entirely on the control function. .PP \&\fBX509_LOOKUP_set_get_by_subject()\fR, \fBX509_LOOKUP_set_get_by_issuer_serial()\fR, \&\fBX509_LOOKUP_set_get_by_fingerprint()\fR, \fBX509_LOOKUP_set_get_by_alias()\fR 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. .PP Implementations must add objects they find to the \fBX509_STORE\fR object using \fBX509_STORE_add_cert()\fR or \fBX509_STORE_add_crl()\fR. This increments its reference count. However, the \fBX509_STORE_CTX_get_by_subject()\fR function also increases the reference count which leads to one too many references being held. Therefore, applications should additionally call \fBX509_free()\fR or \fBX509_CRL_free()\fR to decrement the reference count again. .PP Implementations should also use either \fBX509_OBJECT_set1_X509()\fR or \&\fBX509_OBJECT_set1_X509_CRL()\fR to set the result. Note that this also increments the result's reference count. .PP Any method data that was created as a result of the new_item function set by \fBX509_LOOKUP_meth_set_new_item()\fR can be accessed with \&\fBX509_LOOKUP_get_method_data\fR\|(3). The \fBX509_STORE\fR object that owns the X509_LOOKUP may be accessed with \fBX509_LOOKUP_get_store\fR\|(3). Successful lookups should return 1, and unsuccessful lookups should return 0. .PP \&\fBX509_LOOKUP_get_get_by_subject()\fR, \fBX509_LOOKUP_get_get_by_issuer_serial()\fR, \&\fBX509_LOOKUP_get_get_by_fingerprint()\fR, \fBX509_LOOKUP_get_get_by_alias()\fR retrieve the function set by the corresponding setter. .SH "RETURN VALUES" .IX Header "RETURN VALUES" The \fBX509_LOOKUP_meth_set\fR functions return 1 on success or 0 on error. .PP The \fBX509_LOOKUP_meth_get\fR functions return the corresponding function pointers. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBX509_STORE_new\fR\|(3), \fBSSL_CTX_set_cert_store\fR\|(3) .SH "HISTORY" .IX Header "HISTORY" The functions described here were added in OpenSSL 1.1.0i. .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2018\-2020 The OpenSSL Project Authors.
