Note: this is defined by standards (X.509 et al) to be one less than the certificate version. So a version 3 certificate will return 2 and a version 1 certificate will return 0.</p> <p>X509_set_version() sets the numerical value of the version field of certificate <b>x</b> to <b>version</b>.</p> <p>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.</p> <h1 id="NOTES">NOTES</h1> <p>The version field of certificates, certificate requests and CRLs has a DEFAULT value of <b>v1(0)</b> meaning the field should be omitted for version 1.
