TLS-o-matic started as a series of SIP – IP telephony – protocol tests at the SIPit test events. After a while, the idea of making these available for application developers using HTTP grew and we started creating a series of tests for web browsers, applications both on mobile and ordinary computers as well as the Curl and libCURL users.

What can you do on this site?

On this site you can learn more about TLS, The Transport Layer Security protocol that has replaced the old SSL protocol, and run a set of tests that will teach you more, as well as challenge your applications in a number of ways.
