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. 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
