# gnutls\_srp\_set\_prime\_bits(3)

API function

## NAME

gnutls\_srp\_set\_prime\_bits - API function

## SYNOPSIS

**#include \<gnutls/gnutls.h\>**

**void gnutls\_srp\_set\_prime\_bits(gnutls\_session\_t** *session***, unsigned int** *bits***);**

## ARGUMENTS

- gnutls\_session\_t session

  is a **gnutls\_session\_t** type.

- unsigned int bits

  is the number of bits

## DESCRIPTION

This function sets the minimum accepted number of bits, for use in an SRP key exchange.  If zero, the default 2048 bits will be used.

In the client side it sets the minimum accepted number of bits.  If a server sends a prime with less bits than that **GNUTLS\_E\_RECEIVED\_ILLEGAL\_PARAMETER** will be returned by the handshake.

This function has no effect in server side.
