X509V3_CACHE_EXTENSIONS(3SSL) OpenSSL X509V3_CACHE_EXTENSIONS(3SSL)

NAME

X509v3_cache_extensions - process any extensions in an X509 object

SYNOPSIS

 #include <openssl/x509v3.h>
 int X509v3_cache_extensions(X509 *x, OPENSSL_CTX *libctx, const char *propq);

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 x and the library context and property query string to use are given in libctx and propq.

RETURN VALUES

This function returns 0 if the extensions are invalid or an error occurred. Otherwise it returns 1.
