gnutls_x509_t...t_verify_crt2(3) gnutls gnutls_x509_t...t_verify_crt2(3)
gnutls_x509_trust_list_verify_crt2 - API function
#include <gnutls/x509.h>
int gnutls_x509_trust_list_verify_crt2(gnutls_x509_trust_list_t
list, gnutls_x509_crt_t * cert_list, unsigned int cert_list_size,
gnutls_typed_vdata_st * data, unsigned int elements, unsigned int
flags, unsigned int * voutput, gnutls_verify_output_function
func);
gnutls_x509_trust_list_t list
The list
gnutls_x509_crt_t * cert_list
is the certificate list to be verified
unsigned int cert_list_size
is the certificate list size
gnutls_typed_vdata_st * data
an array of typed data
unsigned int elements
the number of data elements
unsigned int flags
Flags that may be used to change the verification
algorithm. Use OR of the
gnutls_certificate_verify_flags enumerations.
unsigned int * voutput
will hold the certificate verification output.
gnutls_verify_output_function func
If non-null will be called on each chain element
verification with the output.
This function will attempt to verify the given certificate chain
and return its status. The voutput parameter will hold an OR'ed
sequence of gnutls_certificate_status_t flags.
When a certificate chain of cert_list_size with more than one
certificates is provided, the verification status will apply to
the first certificate in the chain that failed verification. The
verification process starts from the end of the chain (from CA to
end certificate). The first certificate in the chain must be the
end-certificate while the rest of the members may be sorted or
not.
Additionally a certificate verification profile can be specified
from the ones in gnutls_certificate_verification_profiles_t by
ORing the result of GNUTLS_PROFILE_TO_VFLAGS() to the
verification flags.
Additional verification parameters are possible via the data
types; the acceptable types are GNUTLS_DT_DNS_HOSTNAME,
GNUTLS_DT_IP_ADDRESS and GNUTLS_DT_KEY_PURPOSE_OID. The former
accepts as data a null-terminated hostname, and the latter a
null-terminated object identifier (e.g.,
GNUTLS_KP_TLS_WWW_SERVER). If a DNS hostname is provided then
this function will compare the hostname in the end certificate
against the given. If names do not match the
GNUTLS_CERT_UNEXPECTED_OWNER status flag will be set. In addition
it will consider certificates provided with
gnutls_x509_trust_list_add_named_crt().
If a key purpose OID is provided and the end-certificate contains
the extended key usage PKIX extension, it will be required to
match the provided OID or be marked for any purpose, otherwise
verification will fail with GNUTLS_CERT_PURPOSE_MISMATCH status.
On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a
negative error value. Note that verification failure will not
result to an error code, only voutput will be updated.
