ne_ssl_dname
NE_SSL_CERTIFICATE(3) neon API reference NE_SSL_CERTIFICATE(3)NAME
ne_ssl_certificate, ne_ssl_dname - structures representing SSL certificates
SYNOPSIS
#include <ne_session.h>
/* A simplified X.509 distinguished name. */
typedef struct {
const char *country, *state, *locality, *organization;
const char *organizationalUnit;
const char *commonName;
} ne_ssl_dname;
/* A simplified SSL certificate. */
typedef struct {
const ne_ssl_dname *subject, *issuer;
const char *from, *until;
} ne_ssl_certificate;
DESCRIPTION
The ne_ssl_dname structure is used to represent a simplified X.509 distinguished name, as used in SSL certificates; a distinguished name is
used to uniquely identify an entity. Along with the fields giving the geographical and organizational location of the entity, the common-
Name field will be assigned the DNS hostname of the entity. The ne_ssl_readable_dname function can be used to create a single-line string
out of an ne_ssl_dname structure.
The ne_ssl_certificate structure is used to represent a simplified SSL certificate; containing the distinguished names of the issuer and
subject of the certificate. The issuer is the entity which has digitally signed the certificate to guarantee its authenticity; the subject
is the owner of the certificate. A certificate is only valid for a certain period of time: the from and until contain strings giving the
validity period.
