| X509_GET_VERSION(3ossl) | OpenSSL | X509_GET_VERSION(3ossl) |
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 versionSYNOPSIS
#include <openssl/x509.h> long X509_get_version(const X509 *x); int X509_set_version(X509 *x, long version); long X509_REQ_get_version(const X509_REQ *req); int X509_REQ_set_version(X509_REQ *x, long version); long X509_CRL_get_version(const X509_CRL *crl); int X509_CRL_set_version(X509_CRL *x, long version);
DESCRIPTION
X509_get_version() returns the numerical value of the version field of certificate x. These correspond to the constants X509_VERSION_1, X509_VERSION_2, and X509_VERSION_3. Note: the values of these constants are defined by standards (X.509 et al) to be one less than the certificate version. So X509_VERSION_3 has value 2 and X509_VERSION_1 has value 0.X509_set_version() sets the numerical value of the version field of certificate x to 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. They use constants X509_REQ_VERSION_1, X509_CRL_VERSION_1, and X509_CRL_VERSION_2.
NOTES
The version field of certificates, certificate requests and CRLs has a DEFAULT value of v1(0) meaning the field should be omitted for version 1. This is handled transparently by these functions.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.
