+=head1 NAME
+
+X509V3_EXT_nconf, X509V3_EXT_nconf_nid - functions to
+create X.509 certificate extensions based on OpenSSL configuration
+
+
+=head1 SYNOPSIS
+
+ #include <openssl/x509v3.h>
+
+ X509_EXTENSION *X509V3_EXT_nconf_nid(CONF *conf, X509V3_CTX *ctx, int ext_nid,
+     const char *value);
+ X509_EXTENSION *X509V3_EXT_nconf(CONF *conf, X509V3_CTX *ctx, const char *name,
+     const char *value);
+
+=head1 DESCRIPTION
+
+X509V3_EXT_nconf_nid() and X509V3_EXT_nconf() create a requested X.509
+extension identified either by I<name> or I<ext_nid> correspondingly using
+I<value> contains the string to encode.
+
+I<conf> the configuration information where additional data
+will be read from. I<conf> will typically come from a config
+file.
+
+In case when I<ctx> value is null, the default one is used.
+
+=head1 NOTES
+
+Normally these functions should not be called directly. For many extensions
+they will not produce the expected results without a suitably configured
+context (I<conf> and I<ctx> arguments) that specifies the target object, issuer
+data etc.
+
+=head1 RETURN VALUES
+
+X509V3_EXT_nconf() and X509V3_EXT_nconf_nid() return an B<X509_EXTENSION>
+object on success and NULL on failure.
