NAME

6       gnutls_handshake_set_max_packet_length - API function
7

SYNOPSIS

9       #include <gnutls/gnutls.h>
10
11       void  gnutls_handshake_set_max_packet_length(gnutls_session_t  session,
12       size_t max);
13

ARGUMENTS

15       gnutls_session_t session
16                   is a gnutls_session_t type.
17
18       size_t max  is the maximum number.
19

DESCRIPTION

21       This function will set the maximum  size  of  all  handshake  messages.
22       Handshakes   over   this   size   are   rejected   with  GNUTLS_E_HAND‐
23       SHAKE_TOO_LARGE error code.  The default value is 128kb which is  typi‐
24       cally  large  enough.  Set this to 0 if you do not want to set an upper
25       limit.
26
27       The reason for restricting the handshake message sizes are to limit De‐
28       nial of Service attacks.
29
30       Note  that  the maximum handshake size was increased to 128kb from 48kb
31       in GnuTLS 3.5.5.
