=head1 NAME

|
|
|
x509 - X.509 certificate handling
|
|
|
|
=head1 SYNOPSIS
|
|
|
|
#include <openssl/x509.h>
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
An X.509 certificate is a structured grouping of information about
|
|
an individual, a device, or anything one can imagine. A X.509 CRL
|
|
(certificate revocation list) is a tool to help determine if a
|
|
certificate is still valid. The exact definition of those can be
|
|
found in the X.509 document from ITU-T, or in RFC3280 from PKIX.
|
|
In OpenSSL, the type X509 is used to express such a certificate, and
|
|
the type X509_CRL is used to express a CRL.
|
|
|
|
A related structure is a certificate request, defined in PKCS#10 from
|
|
RSA Security, Inc, also reflected in RFC2896. In OpenSSL, the type
|
|
X509_REQ is used to express such a certificate request.
|
|
|
|
To handle some complex parts of a certificate, there are the types
|
|
X509_NAME (to express a certificate name), X509_ATTRIBUTE (to express
|
|
a certificate attributes), X509_EXTENSION (to express a certificate
|
|
extension) and a few more.
|
|
|
|
Finally, there's the supertype X509_INFO, which can contain a CRL, a
|
|
certificate and a corresponding private key.
|
|
|
|
B<X509_>I<...>, B<d2i_X509_>I<...> and B<i2d_X509_>I<...> handle X.509
|
|
certificates, with some exceptions, shown below.
|
|
|
|
B<X509_CRL_>I<...>, B<d2i_X509_CRL_>I<...> and B<i2d_X509_CRL_>I<...>
|
|
handle X.509 CRLs.
|
|
|
|
B<X509_REQ_>I<...>, B<d2i_X509_REQ_>I<...> and B<i2d_X509_REQ_>I<...>
|
|
handle PKCS#10 certificate requests.
|
|
|
|
B<X509_NAME_>I<...> handle certificate names.
|
|
|
|
B<X509_ATTRIBUTE_>I<...> handle certificate attributes.
|
|
|
|
B<X509_EXTENSION_>I<...> handle certificate extensions.
