TLS version 0.3.1
Important News! UserLand Software Acquires TLS


TLS 0.3.1 Released

NOTE: This is prerelease software. The contents of the first full release may be significantly different from what is available here. Watch for updates.

TLS stands for "Transport Layer Security". It includes SSL, and is the proposed standard that is superceding SSL.

Macrobyte's TLS provides client side tools for making secure HTTPS requests, and server side tools for running a secure web server. It also includes tools for creating and managing "keys," self-signed certificates, and "certificate signing requests" (for sending to companies like Verisign, Thawte, or Komodo, to receive a valid server certificate).

System Requirements

TLS requires an up-to-date copy of UserLand Frontier™, or Radio UserLand™, running on Windows, MacOS X, or MacOS 8/9. UserLand offers free 30 day trial versions of both applications if you wish to try out TLS.

License Agreement

A license agreement is included with the software, and it is also available online. Please read the license before installing TLS. If you do not agree to the terms of the license, you must not install the software.


After downloading and expanding the archive, run the "Install TLS" script. See the README document inside the database for examples and other information, or the Getting Started document online.

What's New

Version 0.3.1 fixes several related bugs in the secure webserver, where the server would not acknowledge situations in which the client cancelled the SSL/TLS session.

The most common occurrence of this situation is when the client browser displays a warning that the secure site is not fully trusted, and the user opts to cancel. Previously, the listening thread would remain alive on the server, but would not be useful, and in some situations could cause an apparently deaf server. In this release, an aborted connection is properly cancelled.
