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. + +=head1 SEE ALSO + +L<X509_NAME_ENTRY_get_object(3)|X509_NAME_ENTRY_get_object(3)>, +L<X509_NAME_add_entry_by_txt(3)|X509_NAME_add_entry_by_txt(3)>, +L<X509_NAME_add_entry_by_NID(3)|X509_NAME_add_entry_by_NID(3)>, +L<X509_NAME_print_ex(3)|X509_NAME_print_ex(3)>, +L<X509_NAME_new(3)|X509_NAME_new(3)>, +L<d2i_X509(3)|d2i_X509(3)>, +L<d2i_X509_ALGOR(3)|d2i_X509_ALGOR(3)>, +L<d2i_X509_CRL(3)|d2i_X509_CRL(3)>, +L<d2i_X509_NAME(3)|d2i_X509_NAME(3)>, +L<d2i_X509_REQ(3)|d2i_X509_REQ(3)>, +L<d2i_X509_SIG(3)|d2i_X509_SIG(3)>, +L<crypto(3)|crypto(3)>, +L<x509v3(3)|x509v3(3)> + +=cut |
