Disabling SSLv3 in NTK Plugin (Poodle vulnerability)

There has been a lot of attention in the media about the Poodle vulnerability in the SSL protocol. NTK Plugin supports both the SSLv2, SSLv3 and TLSv1 protocols. Disabling the unsafe protocols is easy. Just include the following in the option list when calling TCP Listen or TCP Open:


This will disable SSLv2 and SSLv3. This issue is most importantly for server sockets. Client sockets will negotiate with the server and negotiate on the protocol to use. If the server tells it only supports TLSv1, then that will be used.

In the upcoming 2.5.4 version we will make TLSv1 the default ssl-method for server sockets.

NTK Plugin 2.5.2 released

NTK Plugin has been updated to version 2.5.2. This release includes several important bug fixes and a few new features. All developers are recommended to update to this version.

New commands have been added to retrieve various information from SSL certificates and enhanced certificate validation. To make life easier for developers, “warnings” are by default no-longer reported to the error handler. This behavior can be controlled using the “verbose” option. On Mac the plugin now uses its own copy of OpenSSL instead of the system provided one. Because of this the plugin is no longer compatible with OS X 10.5. More details can be found in the section Version history of the documentation.
