Contact us - chat with us


In order to communicate over affiliation boundaries, we use skype in the CrypTool 2.0 project. The following public channel (disccusion groups) exists mainly for developers. Hence, if you're a developer and want to contribute to the CrypTool 2.0 project, you should join our skype discussion group in order to always stay up-to-date about the current state of the project. Clearly, you may also join the chat if you are just interested in some technical details - most of the times there is somebody online who is able to help you.

To join, copy and paste the following URI to your web browser (Skype must be installed already):


Hint about Skype public chats: There are two ways how to leave/close a chat you're currently on. If you simply close the window, with the X in the upper right corner, you just closed the window, but you stay joined in the channel. Hence, if somebody types a message, the window will open automatically. However, if you press the Leave button (also in the upper right corner), then you really leave the channel, and you'll miss everything what's going on afterwards (until next join). Hence, the preferred way should be, to simply close the window (not leave) - this way you get a nice history of all ongoing discussions. Additionally, you should mark this chat as a favorite. By doing so you can access it easily at any time.

Mailing list

Note to anonymous users: Replace '...' with the domain name

There is also a mailing list for discussion among CrypTool 2 developers. If you'd like to join, send a mail to listmanager@… with the following subject:

subscribe ct2-dev

To send a message to all subscribers, send a mail to ct2-dev@…. All messages sent over the list are automatically tagged with the string "[ct2-dev]" in the subject, so you can create filter rules in your mail program if you like to.

If you'd like to leave, use the following subject:

unsubscribe ct2-dev

Please note, that the subscribed address and your From-address in your email program must be identical, or the unsubscribe attempt will fail. If you're subscribed with another address (for example if we added a subscription for you with a * alias), please contact ct2-dev-owner@… in order to unsubscribe a foreign mail address.

There is currently no web interface to the mailing list.
