NAME

       gnutls_x509_trust_list_verify_crt2 - API function

SYNOPSIS

       #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);

ARGUMENTS

       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.

DESCRIPTION

       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.

RETURNS

       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.
