First, locate the curity file which your JDK is using.

Please note that this will disable TLS 1.0 & 1.1 for all the applications that depend on the JVM. All we need is to modify a configuration file. This method doesn’t require any change in the code. In this post, I’ll show you how we can disable TLS versions 1.0 & 1.1 in our Java applications so that only TLSv1.2 is used. NET 4.5 installed, your 2.0-4.0 apps will use the 4.5 System.dll and you can enable TLS 1.2 using this code:įtp.SSLConfiguration.EnabledSslProtocols = ()3072 Ĭonsider using our Q&A forum for asking questions.As we know TLS versions 1.0 & 1.1 have been deprecated and replaced with version 1.2, it is imperative for our applications to use TLS 1.2 by default while disabling the other two versions. NET lower than 4.5, but 4.5 must be installed on the machine. It is possible to use TLS 1.2 in applications targeting.

NET Framework 4.5+ must be installed on your machine and you application should target. You first connect to non-secure port (21) and secure the connection using Ftp.AuthTLS command: All you need to do is to set property to SslProtocols.Tls12:įtp.SSLConfiguration.EnabledSslProtocols = SslProtocols.Tls12 įtp.SSLConfiguration.EnabledSslProtocols = SslProtocols.Tls12įtp.Upload('report.txt', 'c: eport.txt')įor explicit SSL/TLS, code is almost the same. It is easy to force the connection to use it. TLS 1.2 is the most secure version of SSL/TLS protocols. By default most systems allow SSL 3.0, TLS 1.0, 1.2 and 1.2 to be used.
