Any algorithm registered will override the included algorithms and by convention kernel implemented algorithms have priority of 90 and CPU\-assisted of 80. The algorithm with the lowest priority will be used by gnutls. .SH "RETURNS" \fBGNUTLS_E_SUCCESS\fP on success, otherwise a negative error code. .SH "SINCE" 3.4.0 .SH "REPORTING BUGS" Report bugs to . .br Home page: https://www.gnutls.org .SH COPYRIGHT Copyright \(co 2001-2021 Free Software Foundation, Inc., and others. .br Copying and distribution of this file, with or without modification, are permitted in any medium without royalty provided the copyright notice and this notice are preserved. .SH "SEE ALSO" The full documentation for .B gnutls is maintained as a Texinfo manual.
