x509(3) 							      OpenSSL								   x509(3)

NAME
x509 - X.509 certificate handling SYNOPSIS
#include <openssl/x509.h> 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. X509_..., d2i_X509_... and i2d_X509_... handle X.509 certificates, with some exceptions, shown below. X509_CRL_..., d2i_X509_CRL_... and i2d_X509_CRL_... handle X.509 CRLs. X509_REQ_..., d2i_X509_REQ_... and i2d_X509_REQ_... handle PKCS#10 certificate requests. X509_NAME_... handle certificate names. X509_ATTRIBUTE_... handle certificate attributes. X509_EXTENSION_... handle certificate extensions. SEE ALSO
X509_NAME_ENTRY_get_object(3), X509_NAME_add_entry_by_txt(3), X509_NAME_add_entry_by_NID(3), X509_NAME_print_ex(3), X509_NAME_new(3), d2i_X509(3), d2i_X509_ALGOR(3), d2i_X509_CRL(3), d2i_X509_NAME(3), d2i_X509_REQ(3), d2i_X509_SIG(3), crypto(3), x509v3(3) 1.0.1e 2013-02-11 x509(3)
