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 structure of 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 try to verify the given certificate and return its status. The verify parameter will hold an OR'ed sequence of gnutls_certificate_status_t flags.

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.

The acceptable data types are GNUTLS_DT_DNS_HOSTNAME 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 certificate against the given. If names do not match the GNUTLS_CERT_UNEXPECTED_OWNER status flag will be set. If a key purpose OID is provided and the end-certificate contains the extended key usage PKIX extension, it will be required to be have the provided key purpose or be marked for any purpose, otherwise verification will fail with GNUTLS_CERT_SIGNER_CONSTRAINTS_FAILURE 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.
