Multiple \fBX509_LOOKUP\fR instances can be added to an \fBX509_STORE\fR\|(3) to enable lookup in that store. .PP \&\fBX509_LOOKUP_new()\fR creates a new \fBX509_LOOKUP\fR using the given lookup \&\fImethod\fR. It can also be created by calling \fBX509_STORE_add_lookup\fR\|(3), which will associate an \fBX509_STORE\fR with the lookup mechanism. .PP \&\fBX509_LOOKUP_init()\fR initializes the internal state and resources as needed by the given \fBX509_LOOKUP\fR to do its work. .PP \&\fBX509_LOOKUP_shutdown()\fR tears down the internal state and resources of the given \fBX509_LOOKUP\fR. .PP \&\fBX509_LOOKUP_free()\fR destructs the given \fBX509_LOOKUP\fR. .PP \&\fBX509_LOOKUP_set_method_data()\fR associates a pointer to application data to the given \fBX509_LOOKUP\fR. .PP \&\fBX509_LOOKUP_get_method_data()\fR retrieves a pointer to application data from the given \fBX509_LOOKUP\fR. .PP \&\fBX509_LOOKUP_ctrl()\fR is used to set or get additional data to or from an \&\fBX509_LOOKUP\fR structure or its associated \fBX509_LOOKUP_METHOD\fR\|(3). The arguments of the control command are passed via \fIargc\fR and \fIargl\fR, its return value via \fI*ret\fR. The meaning of the arguments depends on the \fIcmd\fR number of the control command. In general, this function is not called directly, but wrapped by a macro call, see below. The control \fIcmd\fRs known to OpenSSL are discussed in more depth in \*(L"Control Commands\*(R". .PP \&\fBX509_LOOKUP_load_file()\fR passes a filename to be loaded immediately into the associated \fBX509_STORE\fR. \&\fItype\fR indicates what type of object is expected. This can only be used with a lookup using the implementation \&\fBX509_LOOKUP_file\fR\|(3). .PP \&\fBX509_LOOKUP_add_dir()\fR passes a directory specification from which certificates and CRLs are loaded on demand into the associated \&\fBX509_STORE\fR. \&\fItype\fR indicates what type of object is expected. This can only be used with a lookup using the implementation \&\fBX509_LOOKUP_hash_dir\fR\|(3). .PP \&\fBX509_LOOKUP_load_file()\fR, \fBX509_LOOKUP_add_dir()\fR, \&\fBX509_LOOKUP_add_store()\fR, and \fBX509_LOOKUP_load_store()\fR are implemented as macros that use \fBX509_LOOKUP_ctrl()\fR. .PP \&\fBX509_LOOKUP_by_subject()\fR, \fBX509_LOOKUP_by_issuer_serial()\fR, \&\fBX509_LOOKUP_by_fingerprint()\fR, and \fBX509_LOOKUP_by_alias()\fR look up certificates and CRLs in the \fBX509_STORE\fR\|(3) associated with the \&\fBX509_LOOKUP\fR using different criteria, where the looked up object is stored in \fIret\fR. Some of the underlying \fBX509_LOOKUP_METHOD\fRs will also cache objects matching the criteria in the associated \fBX509_STORE\fR, which makes it possible to handle cases where the criteria have more than one hit. .SS "File Types" .IX Subsection "File Types" \&\fBX509_LOOKUP_load_file()\fR and \fBX509_LOOKUP_add_dir()\fR take a \fItype\fR, which can be one of the following: .IP "\fBX509_FILETYPE_PEM\fR" 4 .IX Item "X509_FILETYPE_PEM" The file or files that are loaded are expected to be in \s-1PEM\s0 format. .IP "\fBX509_FILETYPE_ASN1\fR" 4 .IX Item "X509_FILETYPE_ASN1" The file or files that are loaded are expected to be in raw \s-1DER\s0 format. .IP "\fBX509_FILETYPE_DEFAULT\fR" 4 .IX Item "X509_FILETYPE_DEFAULT" The default certificate file or directory is used. In this case, \&\fIname\fR is ignored. .SS "Control Commands" .IX Subsection "Control Commands" The \fBX509_LOOKUP_METHOD\fRs built into OpenSSL recognise the following \&\fBX509_LOOKUP_ctrl()\fR \fIcmd\fRs: .IP "\fBX509_L_FILE_LOAD\fR" 4 .IX Item "X509_L_FILE_LOAD" This is the command that \fBX509_LOOKUP_load_file()\fR uses. The filename is passed in \fIargc\fR, and the type in \fIargl\fR. .IP "\fBX509_L_ADD_DIR\fR" 4 .IX Item "X509_L_ADD_DIR" This is the command that \fBX509_LOOKUP_add_dir()\fR uses. The directory specification is passed in \fIargc\fR, and the type in \&\fIargl\fR. .IP "\fBX509_L_ADD_STORE\fR" 4 .IX Item "X509_L_ADD_STORE" This is the command that \fBX509_LOOKUP_add_store()\fR uses. The \s-1URI\s0 is passed in \fIargc\fR. .IP "\fBX509_L_LOAD_STORE\fR" 4 .IX Item "X509_L_LOAD_STORE" This is the command that \fBX509_LOOKUP_load_store()\fR uses. The \s-1URI\s0 is passed in \fIargc\fR. .SH "RETURN VALUES" .IX Header "RETURN VALUES" \&\fBX509_LOOKUP_new()\fR returns an \fBX509_LOOKUP\fR pointer when successful, or \s-1NULL\s0 on error. .PP \&\fBX509_LOOKUP_init()\fR and \fBX509_LOOKUP_shutdown()\fR return 1 on success, or 0 on error. .PP \&\fBX509_LOOKUP_ctrl()\fR returns \-1 if the \fBX509_LOOKUP\fR doesn't have an associated \fBX509_LOOKUP_METHOD\fR, or 1 if the doesn't have a control function. Otherwise, it returns what the control function in the \&\fBX509_LOOKUP_METHOD\fR returns, which is usually 1 on success and 0 in error. .IX Xref "509_LOOKUP_METHOD" .PP \&\fBX509_LOOKUP_get_store()\fR returns an \fBX509_STORE\fR pointer if there is one, otherwise \s-1NULL.\s0 .PP \&\fBX509_LOOKUP_by_subject()\fR, \fBX509_LOOKUP_by_issuer_serial()\fR, \&\fBX509_LOOKUP_by_fingerprint()\fR, and \fBX509_LOOKUP_by_alias()\fR all return 0 if there is no \fBX509_LOOKUP_METHOD\fR or that method doesn't implement the corresponding function. Otherwise, it returns what the corresponding function in the \&\fBX509_LOOKUP_METHOD\fR returns, which is usually 1 on success and 0 in error. .SH "SEE ALSO" .IX Header "SEE ALSO" \&\fBX509_LOOKUP_METHOD\fR\|(3), \fBX509_STORE\fR\|(3) .SH "COPYRIGHT" .IX Header "COPYRIGHT" Copyright 2020 The OpenSSL Project Authors.
