SYNOPSIS

9       #include <gnutls/x509.h>
10
11       int         gnutls_x509_crt_verify_data2(gnutls_x509_crt_t         crt,
12       gnutls_sign_algorithm_t algo, unsigned int flags, const  gnutls_datum_t
13       * data, const gnutls_datum_t * signature);
14

ARGUMENTS

16       gnutls_x509_crt_t crt
17                   Holds the certificate to verify with
18
19       gnutls_sign_algorithm_t algo
20                   The signature algorithm used
21
22       unsigned int flags
23                   Zero or an OR list of gnutls_certificate_verify_flags
24
25       const gnutls_datum_t * data
26                   holds the signed data
27
28       const gnutls_datum_t * signature
29                   contains the signature
30

DESCRIPTION

32       This  function  will verify the given signed data, using the parameters
33       from the certificate.
34

RETURNS

36       In case of  a  verification  failure  GNUTLS_E_PK_SIG_VERIFY_FAILED  is
37       returned,  GNUTLS_E_EXPIRED or GNUTLS_E_NOT_YET_ACTIVATED on expired or
38       not yet activated certificate and zero or positive code on success.
39
40       Note that since GnuTLS 3.5.6 this function introduces checks in the end
41       certificate ( crt ), including time checks and key usage checks.
