NAME         top

       gnutls_sign_set_secure - API function

SYNOPSIS         top

       #include <gnutls/gnutls.h>

       int gnutls_sign_set_secure(gnutls_sign_algorithm_t sign, unsigned
       int secure);

ARGUMENTS         top

       gnutls_sign_algorithm_t sign
                   the sign algorithm

       unsigned int secure
                   whether to mark the sign algorithm secure

DESCRIPTION         top

       Modify the previous system wide setting that marked  sign as
       secure or insecure.  Calling this function is allowed only if
       allowlisting mode is set in the configuration file, and only if
       the system-wide TLS priority string has not been initialized yet.
       The intended usage is to provide applications with a way to
       expressly deviate from the distribution or site defaults
       inherited from the configuration file.  The modification is
       composable with further modifications performed through the
       priority string mechanism.

       This function is not thread-safe and is intended to be called in
       the main thread at the beginning of the process execution.

       Even when  secure is true,  sign is not marked as secure for the
       use in certificates.  Use gnutls_sign_set_secure_for_certs() to
       mark it secure as well for certificates.

RETURNS         top

       0 on success or negative error code otherwise.
