Set up Lets Encrypt on Debian/Ubuntu Linux.

This entry is 10 of 14 in the Secure Web Server with Let's Encrypt Tutorial series. See Nginx web server docs here for more info. with the Nginx web server running on Linux or Unix like systems. You successfully configured and enabled TLS 1. See curl man page here or type the following man command:

-tls-max VERSION : Set maximum allowed TLS version.

In this final example, check and use Nginx use TLS 1.0/1.1: * Connection #0 to host left intact Test Nginx TLS 1.1/1.0 support (must fail) Strict-transport-security: max-age=15552000 < strict-transport-security: max-age=15552000 * Connection state changed (MAX_CONCURRENT_STREAMS = 256)! * TLSv1.3 (IN), TLS handshake, Newsession Ticket (4): * Copying HTTP/2 data in stream buffer to connection buffer after upgrade: len=0 * Connection state changed (HTTP/2 confirmed) * issuer: C=US ST=CA L=San Francisco O=CloudFlare, Inc. * subjectAltName: host 'matched cert 's '*.' * subject: C = US ST=CA L=San Francisco O=Cloudflare, Inc. * SSL connection using TLSv1.3 / TLS_AES_256_GCM_SHA384 * TLSv1.3 (OUT ), TLS handshake, Finished ( 20 ): * TLSv1.3 (OUT ), TLS change cipher, Change cipher spec ( 1 ): * TLSv1.3 (IN ), TLS handshake, Finished ( 20 ): * TLSv1.3 (IN ), TLS handshake, CERT verify ( 15 ): * TLSv1.3 (IN ), TLS handshake, Certificate ( 11 ): * TLSv1.3 (IN ), TLS handshake, Encrypted Extensions ( 8 ): * TLSv1.3 (IN ), TLS handshake, Server hello ( 2 ): * TLSv1.3 (OUT ), TLS handshake, Client hello ( 1 ):

Server ssl_certificate /etc/nginx/ssl/fullchain.pem Just enable TLS version 1.3 in nginx: ssl_protocols TLSv1.3

#Test tls 1.2 on server how to#

How to Enable TLS 1.3 in Nginxįor both TLS version 1.2 and 1.3 use the following in nginx config file: ssl_protocols TLSv1.2 TLSv1.3 # replace with the IP address of your resolver Ssl_trusted_certificate /etc/nginx/ssl/fullchain.pem # verify chain of trust of OCSP response using Root CA and Intermediate certs The TLSv1.3 parameter (1.13.0) works only when OpenSSL 1.1.1 built with TLSv1.3 support is used. Please note that the TLSv1.1 and TLSv1.2 parameters (1.1.13, 1.0.12) work only when OpenSSL 1.0.1 or higher is used. $ openssl version OpenSSL 1.1.1d How To enable TLS 1.2 only in Nginx web server $ nginx -v nginx version: nginx/1.16.1 How to check OpenSSL version Hence, I recommend enabling both 1.2 and 1.3 support in Nginx.

#Test tls 1.2 on server android#

TLS 1.3 only supports Firefox 63+, Android 10.0+, Chrome 70+, Edge 75, Java 11, OpenSSL 1.1.1, Opera 57, and Safari 12.1.

#Test tls 1.2 on server windows#

In other words, an older client from Windows XP or an older version of Android/Java won’t work. I tested the server configuration with the following components:Īs a result, this config option works the following clients only:

We can combine and only allow TLS 1.2 and 1.3 in Nginx by setting: ssl_protocols TLSv1.2 TLSv1.3 Ī note about our set up for TLS 1.2 or 1.3 only in Nginx web server.

For TLS version 1.3 by add ssl_protocols TLSv1.3.

Set TLS version by editing ssl_protocols TLSv1.2.

Edit nf file or virtual domain config file.
