=head1 NAME
|
|
|
|
X509_get_version, X509_set_version, X509_REQ_get_version, X509_REQ_set_version,
|
|
X509_CRL_get_version, X509_CRL_set_version - get or set certificate,
|
|
certificate request or CRL version.
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/x509.h>
|
|
|
|
long X509_get_version(X509 *x);
|
|
int X509_set_version(X509 *x, long version);
|
|
|
|
long X509_REQ_get_version(X509_REQ *req);
|
|
int X509_REQ_set_version(X509_REQ *x, long version);
|
|
|
|
long X509_CRL_get_version(X509_CRL *crl);
|
|
int X509_CRL_set_version(X509_CRL *x, long version);
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
X509_get_version() returns the numerical value of the version field of
|
|
certificate B<x>. Note: this is defined by standards (X.509 et al) to be one
|
|
less than the certificate version. So a verson 3 certificate will return 2 and
|
|
a version 1 certificate will return 0.
|
|
|
|
X509_set_version() sets the numerical value of the version field of certificate
|
|
B<x> to B<version>.
|
|
|
|
Similarly X509_REQ_get_version(), X509_REQ_set_version(),
|
|
X509_CRL_get_version() and X509_CRL_set_version() get and set the version
|
|
number of certificate requests and CRLs.
|
|
|
|
=head1 NOTES
|
|
|
|
The version field of certificates, certificate requests and CRLs has a
|
|
DEFAULT value of B<v1(0)> meaning the field should be omitted for version
|
|
1. This is handled transparently by these functions.
|
|
|
|
=head1 RETURN VALUES
|
|
|
|
X509_get_version(), X509_REQ_get_version() and X509_CRL_get_version()
|
|
return the numerical value of the version field.
|
|
|
|
X509_set_version(), X509_REQ_set_version() and X509_CRL_set_version()
|
|
return 1 for success and 0 for failure.

=head1 HISTORY
|
|
|
|
X509_get_version(), X509_set_version() X509_REQ_get_version(),
|
|
X509_REQ_set_version(), X509_REQ_get_version() and X509_REQ_set_version()
|
|
are available in all versions of OpenSSL.
|
|
|
|
X509_get_version(), X509_REQ_get_version() and X509_CRL_get_version() are
|
|
functions in OpenSSL 1.1.0, in previous versions they were macros.
