NAME

       gnutls_privkey_sign_data2 - API function

SYNOPSIS

       #include <gnutls/abstract.h>

       int   gnutls_privkey_sign_data2(gnutls_privkey_t   signer,  gnutls_sign_algorithm_t  algo,
       unsigned int flags, const gnutls_datum_t * data, gnutls_datum_t * signature);

ARGUMENTS

       gnutls_privkey_t signer
                   Holds the key

       gnutls_sign_algorithm_t algo
                   The signature algorithm used

       unsigned int flags
                   Zero or one of gnutls_privkey_flags_t

       const gnutls_datum_t * data
                   holds the data to be signed

       gnutls_datum_t * signature
                   will contain the signature allocated with gnutls_malloc()

DESCRIPTION

       This function will sign the given data  using  the  specified  signature  algorithm.  This
       function  is  an  enhancement  of  gnutls_privkey_sign_data(),  as  it  allows utilizing a
       alternative signature algorithm where possible (e.g, use an RSA key with RSA-PSS).

RETURNS

       On success, GNUTLS_E_SUCCESS (0) is returned, otherwise a negative error value.

SINCE

       3.6.0
