- =head1 NAME
- x509 - X.509 certificate handling
- =head1 SYNOPSIS
- #include <openssl/x509.h>
- =head1 DESCRIPTION
- A 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.
