X509v3_cache_extensions
|
||
|
|
- process any extensions in an X509 object
|

|
|

|
|
=head1 SYNOPSIS
|
||
|
|
|
||
|
|
#include <openssl/x509v3.h>
|
||
|
|
|
||
|
|
int X509v3_cache_extensions(X509 *x, OPENSSL_CTX *libctx, const char *propq);
|
||
|
|
|
||
|
|
=head1 DESCRIPTION
|
||
|
|
|
||
|
|
This function processes any X509v3 extensions that might be present in an X509
|
||
|
|
object and caches the result of that processing. Many OpenSSL functions that use
|
||
|
|
an X509 object will cause extensions to be processed and cached implicitly. If
|
||
|
|
this is done implicitly then the default library context and property query
|
||
|
|
string will be used. In some cases it may be desirable to use some other library
|
||
|
|
context and property query string. If so then an application can call
|
||
|
|
X509v3_cache_extensions() explicitly. This should be done before any function
|
||
|
|
that needs to use those extensions is called - otherwise calling
|
||
|
|
X509v3_cache_extensions() will have no effect. Typically this means calling this
|
||
|
|
soon after creation of the X509 object. The X509 object to be processed is
|
||
|
|
given in I<x> and the library context and property query string to use are given
|
||
|
|
in I<libctx> and I<propq>.
|
||
|
|
|
||
|
|
=head1 RETURN VALUES
|
||
|
|
|
||
|
|
This function returns 0 if the extensions are invalid or an error occurred.
|
||
|
|
Otherwise it returns 1.
