24 X509_get_version() returns the numerical value of the version field of
25 certificate B<x>. These correspond to the constants B<X509_VERSION_1>,
26 B<X509_VERSION_2>, and B<X509_VERSION_3>. Note: the values of these constants
27 are defined by standards (X.509 et al) to be one less than the certificate
28 version. So B<X509_VERSION_3> has value 2 and B<X509_VERSION_1> has value 0.
30 X509_set_version() sets the numerical value of the version field of certificate
33 Similarly X509_REQ_get_version(), X509_REQ_set_version(),
34 X509_CRL_get_version() and X509_CRL_set_version() get and set the version
35 number of certificate requests and CRLs. They use constants
36 B<X509_REQ_VERSION_1>, B<X509_CRL_VERSION_1>, and B<X509_CRL_VERSION_2>.
40 The version field of certificates, certificate requests and CRLs has a
41 DEFAULT value of B<v1(0)> meaning the field should be omitted for version
42 1. This is handled transparently by these functions.
46 X509_get_version(), X509_REQ_get_version() and X509_CRL_get_version()
47 return the numerical value of the version field.
49 X509_set_version(), X509_REQ_set_version() and X509_CRL_set_version()
50 return 1 for success and 0 for failure.
