gnutls_handshake_set_max_packet_length(3) API function


#include <gnutls/gnutls.h>

void gnutls_handshake_set_max_packet_length(gnutls_session_t session, size_t max);


gnutls_session_t session
is a gnutls_session_t type.
size_t max
is the maximum number.


This function will set the maximum size of all handshake messages. Handshakes over this size are rejected with GNUTLS_E_HANDSHAKE_TOO_LARGE error code. The default value is 48kb which is typically large enough. Set this to 0 if you do not want to set an upper limit.

The reason for restricting the handshake message sizes are to limit Denial of Service attacks.
