NAME

6       gnutls_pubkey_verify_hash2 - API function
7

SYNOPSIS

9       #include <gnutls/abstract.h>
10
11       int  gnutls_pubkey_verify_hash2(gnutls_pubkey_t  key, gnutls_sign_algo‐
12       rithm_t algo, unsigned int flags, const gnutls_datum_t  *  hash,  const
13       gnutls_datum_t * signature);
14

ARGUMENTS

16       gnutls_pubkey_t key
17                   Holds the public key
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 * hash
26                   holds the hash digest to be verified
27
28       const gnutls_datum_t * signature
29                   contains the signature
30

DESCRIPTION

32       This function will verify the given signed digest, using the parameters
33       from the public key. Note that unlike gnutls_privkey_sign_hash(),  this
34       function  accepts  a signature algorithm instead of a digest algorithm.
35       You can use gnutls_pk_to_sign() to get the appropriate value.
36

RETURNS

38       In case of a verification failure GNUTLS_E_PK_SIG_VERIFY_FAILED is  re‐
39       turned,  and zero or positive code on success. For known to be insecure
40       signatures this function will return GNUTLS_E_INSUFFICIENT_SECURITY un‐
41       less the flag GNUTLS_VERIFY_ALLOW_BROKEN is specified.
