I’have taken over the domain screenfreeze.net due to Andreas Wilhelm’ sudden death which came unexpected.
I would like to thank him for his work and emphasize, that all content under this domain has been published by him, Andreas Wilhelm, also if I have changed the author mapping of the article objects because of technical reasons.
My condolence to his family!
On the 15th of January 2014 our Domain “screenfreeze.net” and Webspace will move to a different Registrar. Some downtime is to be expected, just use this address http://www.screenfreeze.de/ instead.
First of all, I’m not a Security Expert, I just use the well known Encryption and Security standards. So if you find any flaws in how I implemented that stuff, please tell me.
Basically I use self-signed Certificates with a TLSv1.2 SSL Connection. During the “pair”-Process, Desktop and mobile Device exchange their X509v3 Certificate and print out the Fingerprints (sha256), so that the User can verify their Identity. If the User says they match, the Certificates will be stored.
The Certificates are generated from a 2048-bit RSA Key-pair and signed with SHA256 Algorithm.
The SSL Connection is actually over TLSv1,TLSv1.1 or TLSv1.2 depending on your Android Version (TLSv1.2 is supported in Android 4.1 and up) and the OpenSSL Library Version. Server and Client have to authenticate each other with the mentioned Certificates.
So the whole data Transfer is encrypted and the Devices (Desktop and MID) can be sure they talk with the right Machine.
Just released our Smart Howl App for Android. It is designed for mute People or People having problems with speaking. The Application let’s you talk with someone via Text-to-Speech. You can say already stored Texts or build new Sentences by simply drag and drop the Text you need.
Here’s an example Video of how you can use it:
New Features are already planned and are coming soon.
Please check out our Smart Howl Page for more Details on this Product.
So, this is the first Post on our new Development-Blog. Here, we will announce new Projects, Features and Status of Development. Also Support and Information on our Stuff will be published on this Blog. We plan to make closed and open Source Software of various Categories in the Future.
The first Project to be announced is an Android Application called Smart Howl, details on that are coming in the next few Days, stay tuned 😉
