Which versions of Java support TLS 1.2?
| Java Version | TLS 1.2 Support |
|---|---|
| 5 and earlier | Not Supported |
| Java 6 or Java 7 | Supported with
changes |
| Java 8 | Supported |
Note that it's usually best to simply upgrade to Java 8.
Which version of Java does ColdFusion use?
See below for a table of the default Java version for each supported version of ColdFusion
| ColdFusion Version | Default Java Version |
|---|---|
| ColdFusion 10 | Java 6 |
| ColdFusion 11 | Java 7 |
| ColdFusion 2016 | Java 8 |
You can determine exactly which version of Java you're using with the below code.
<cfoutput>#CreateObject("java", "java.lang.System").getProperty("java.version")#</cfoutput>
The output of this command should look like 1.7.0_51. In this example, the Java version being used is Java 7 update 51.
On our shared servers, reach out to our support team if you have any questions regarding whether your site is ready for TLS 1.2. Most of our shared servers are already using Java 8, and we're upgrading the rest of them. We intend to have the upgrades done before any TLS 1.2 deadlines.
VPS Hosting
Java 5 and earlier
Please let our support team know that you would like your JVM upgraded to Java 8. Note that a major Java upgrade in ColdFusion requires a few changes that aren't well documented.
Java 6 or Java 7
TLSv1.2 can be enabled with an additional java argument in your jvm.config.
-Dhttps.protocols=TLSv1,TLSv1.1,TLSv1.2
This argument will allow ColdFusion to use TLSv1.2, and will keep TLSv1 and TLSv1.1 available for communication with servers that don't yet support TLSv1.2.
Note that it's usually best to simply upgrade to Java 8.
Java 8
Java 8 supports TLS 1.2 without any changes.
ASP.Net
| Framework Version | TLS 1.2 Support |
|---|---|
| 2.0-3.5 | Not Supported |
| 4.0-4.5 | Supported with
changes |
| 4.6 | Supported |
Framework 2.0-3.5
No TLS 1.2 support. You must update to at least framework version 4.0
Framework 4.0
For ASP.Net 4.0, you can use either of the following two methods to enable TLS 1.2 support:
NOTE: .Net Framework 4.5 or above must be installed for this to work. However, your application can still target Framework 4.0.
- Method one - per application support
C# Code:
System.Net.ServicePointManager.SecurityProtocol |=
(SecurityProtocolType)768 | (SecurityProtocolType)3072;
- Method two - server-wide support via registry change - All of our
shared servers have this enabled

Framework 4.5
For ASP.Net 4.5, you can use either of the following two methods to enable TLS 1.2 support:
- Method one - per application support
C# Code:
System.Net.ServicePointManager.SecurityProtocol |=
System.Net.SecurityProtocolType.Tls11 |
System.Net.SecurityProtocolType.Tls12;
- Method two - server-wide support via registry change - All of our
shared servers have this enabled

Framework 4.6
ASP.Net 4.6 supports TLS 1.2 without any changes.
