If something was "present in all versions" of SSLeay, or if it was added to a version of SSLeay (and therefore predates OpenSSL), remove mention of it. Documentation history now starts with OpenSSL. Remove mention of all history before OpenSSL 0.9.8, inclusive. Remove all AUTHOR sections. Reviewed-by: Tim Hudson <tjh@openssl.org>

=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_REQ_get_version() and X509_CRL_get_version() are
|
|
functions in OpenSSL 1.1.0, in previous versions they were macros.
