Checking / Updating Outbound TLS 1.2 Support

Due to changes in security, it may be necessary to update or migrate a site to use TLS 1.2 for outbound connections.  Most notably for a payment gateway.  Please note this only affects outbound connections and is not related to a SSL certificate that may be installed for the site.  For general information, including testing, find the applicable scripting section below (ASP.NET, Classic ASP, or PHP).  If it's necessary to migrate the site to a newer version of Windows or you require assistance with reviewing TLS 1.2 support, please open a ticket with the Support Department.
 
 
Windows Server Version
 
The version of Windows Server, necessary to check for ASP.NET and Classic ASP support, can be ascertained by reviewing the Server Name in the DiscountASP Control Panel, then matching it against the key below.  The Server Type field in the DiscountASP Control Panel will show whether the site is on Windows Server 2008, 2012, or 2016, but the key below will specify whether it's on 2008 R2 or 2012 R2.

ASP.NET
 
The requirements for TLS 1.2 support when using ASP.NET are Windows Server 2012 R2 or 2016, ASP.NET Framework 4.5 or higher and bootstrapping code to set the TLS version.

If a site is hosted on older version of Windows, for migration assistance to Windows 2012 R2 or Windows 2016, please open a ticket with Support.

If a site is using an ASP.NET Framework older than 4.5 it will need to be updated. Note this is a project update rather than the ASP.NET Framework version set in the DiscountASP Control Panel.

To set the TLS version for an outbound connection, add the following to the script making the connection or the global.asax:

System.Net.ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12
More information regarding the last update can be found after the link https://stackoverflow.com/q/28286086.  Also note that the bootstrapping code would have to be updated if TLS requirements were to change in the future.
 
 
Classic ASP
 
For TLS 1.2 support through Classic ASP, the site should be on a Windows 2012 R2 or Windows 2016 server.
 
To test TLS 1.2, the script in zssl.zip may be used:  zssl.zip
 
For migration assistance to Windows 2012 R2 or Windows 2016, please open a ticket with Support.
 
 
PHP / cURL
 
For PHP, TLS 1.2 support is dependent on the version of PHP set for the site.  Which should be set to 5.5 or newer in the DiscountASP Control Panel.
 
DiscountASP Control Panel > IIS Tools > PHP Version (drop-down)
 
To test TLS 1.2, the script in zcurl.zip may be used:  zcurl.zip
