Hi, We are using 1.10.3 nginx in FIPS mode. As discussed above we already have FIPS enabled on RHEL and we have recompiled nginx with OpenSSL FIPS. However we still see that Nginx is using MD5 algorithms ( which is not allowed in FIPS mode ) when we use proxy_cache to cache pictures . Looks like nginx uses MD5 hash to create the name of the cached image file. As given in this link httpby kirti maindargikar - Nginx Mailing List - English
