NAME

6       gnutls_x509_crt_get_verify_algorithm  - get hash algorithm used to ver‐
7       ify signature.
8

SYNOPSIS

10       #include <gnutls/x509.h>
11
12       int gnutls_x509_crt_get_verify_algorithm(gnutls_x509_crt_t  crt,  const
13       gnutls_datum_t * signature, gnutls_digest_algorithm_t * hash);
14

ARGUMENTS

16       gnutls_x509_crt_t crt
17                   Holds the certificate
18
19       const gnutls_datum_t * signature
20                   contains the signature
21
22       gnutls_digest_algorithm_t * hash
23                   The  result  of  the  call with the hash algorithm used for
24                   signature
25

DESCRIPTION

27       This function will read the certifcate and the signed data to determine
28       the hash algorithm used to generate the signature.
29

RETURNS

31       the  0  if the hash algorithm is found. A negative value is returned on
32       error.
33

SINCE

35       2.8.0
