FIPS support in nginx?

[kirti maindargikar]

This is the entry in the nginx.conf which is using proxy cache . I dont see
any option here to configure hashing algorithm 

location /nginx-picture {
   internal;
   proxy_buffering on;
   proxy_cache media;
   proxy_cache_key $uri$args;
   proxy_cache_valid 200 43200s;
   proxy_ignore_headers Expires;
   proxy_ignore_headers Cache-Control;
   add_header X-Cache-Status $upstream_cache_status;
   proxy_pass http://acs_backend$request_uri;
}
