=head1 SYNOPSIS
uint32_t X509_get_key_usage(X509 *x);
uint32_t X509_get_extended_key_usage(X509 *x);
const ASN1_OCTET_STRING *X509_get0_subject_key_id(X509 *x);
+ void X509_set_proxy_flag(X509 *x);
+ void X509_set_proxy_path_length(int l);
+ long X509_get_proxy_pathlen(X509 *x);
=head1 DESCRIPTION
identifier of B<x> as an B<ASN1_OCTET_STRING> or B<NULL> if the extension
is not present or cannot be parsed.
+X509_set_proxy_flag() marks the certificate with the B<EXFLAG_PROXY> flag.
+This is for the users who need to mark non-RFC3820 proxy certificates as
+such, as OpenSSL only detects RFC3820 compliant ones.
+
+X509_set_proxy_pathlen() sets the proxy certificate path length for the given
+certificate B<x>. This is for the users who need to mark non-RFC3820 proxy
+certificates as such, as OpenSSL only detects RFC3820 compliant ones.
+
+X509_get_proxy_pathlen() returns the proxy certificate path length for the
+given certificate B<x> if it is a proxy certicate.
+
=head1 NOTES
The value of the flags correspond to extension values which are cached
pointer to an B<ASN1_OCTET_STRING> structure or B<NULL> if the extension
is absent or an error occurred during parsing.
+X509_get_proxy_pathlen() returns the path length value if the given
+certificate is a proxy one and has a path length set, and -1 otherwise.
