# gnutls\_register\_md5\_handler(3)

API function

## NAME

gnutls\_register\_md5\_handler - API function

## SYNOPSIS

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

**int gnutls\_register\_md5\_handler(** *void***);**

## ARGUMENTS

- void

  ## DESCRIPTION

Register a non-libgcrypt based MD5 and HMAC-MD5 handler.  This is useful if you run Libgcrypt in FIPS-mode.  Normally TLS requires use of MD5, so without this you cannot use GnuTLS with libgcrypt in FIPS mode.

## RETURNS

## SINCE

2\.6.0
