Supported SSL/TLS versions

Section titled “Supported SSL/TLS versions”

NGINX Plus supports the following SSL/TLS protocols:

  • SSLv2
  • SSLv3
  • TLSv1
  • TLSv1.1
  • TLSv1.2
  • TLSv1.3

You can configure which protocols to enable or disable with the ssl_protocols directive.

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

TLSv1.3 is supported starting from NGINX Plus R17 and is enabled by default in NGINX Plus R29 and later. It requires OpenSSL 1.1.1 or higher. Note that not all operating systems supported by NGINX Plus include OpenSSL 1.1.1. Check your operating system’s documentation to confirm TLSv1.3 compatibility.

TLSv1.2 and TLSv1.3 are the default SSL protocols starting from NGINX Plus R34 (if supported by the OpenSSL library). If OpenSSL 1.0.0 or older is used, the default SSL protocols are TLSv1 and TLSv1.1.
