Supported SSL/TLS Versions

NGINX Plus supports SSLv2, SSLv3, TLSv1, TLSv1.1, TLSv1.2, and TLSv1.3. Configure the choice of enabled protocols with the ssl_protocols directive.

TLSv1.2 and earlier is supported on all the operating systems listed in Supported Distributions.

NGINX Plus R17 and later support TLSv1.3, and since NGINX Plus R29 it is enabled by default. However, not all operating systems supported by NGINX Plus ship with OpenSSL 1.1.1 as required to support TLSv1.3. To determine if an operating system supports TLSv1.3, consult the vendor documentation.

Supported Deployment Environments

  • Bare metal
  • Container
  • Public cloud: AWS, Google Cloud Platform, Microsoft Azure
  • Virtual machine

See Sizing Guide for Deploying NGINX Plus on Bare Metal Servers
