SafetyJabber program is a standard jabber-client with the integrated encryption, which you can download from our website and install on your computer. It should be said that this program will help you to protect your correspondence safely.
It is necessary to mention that to create this client, the latest achievements of cryptography, methods of data sending and receiving, and techniques of user's interface creation were applied. It is based on WPF (Windows Presentation Foundation) and XAML language that makes it possible to create interfaces of a new generation for modern and following Windows versions. It is important to note that WPF is an ideological continuation of .NET framework.
We receive a lot of questions on our e-mail related to this program. Answers to frequent asked questions will be presented below.
How does encryption work?
Encryption works by the aid of OpenPGP system, which is based on PGP (Pretty Good Privacy) – library of functions, due to which message encryption is carried out. This is a cryptosystem of the asymmetric encryption, so it uses two keys – open, for encryption, and closed, for data decryption. In this way, users, who wish their correspondence to be confidential, just exchange open (public) keys and send each other messages encrypted by these keys. When a user receives such message, he uses his closed (private) key for data decryption. The system guarantees privacy keeping a closed (private) key confidential. It should be realized that you can set the length of the key by yourself and control it. The program is supplied with performed actions viewing mode. It means that you can see on your display how message encryption is carried out.
Why do we need encryption message history?
This question is more rhetoric as many people do not understand the sense of message history without encryption. They have to invent different variants of protecting their personal information. A simple method of using your correspondence for the third persons' own purposes may serve as an example of usefulness of message history encryption.
You leave your working place for thirty minutes to fulfill an urgent order of your boss. As you are very busy and absent-minded, you forget to switch off your computer,your personal correspondence with colleagues and friends that contains some compromising information is kept on the hard disk drive. During this time the third person receives an access to the correspondence, which is decrypted and open.
history encryption function is available in the pay version of SafetyJabber program.
How is data sending carried out?
SafetyJabber uses XMPP protocol for sending messages. After implementing XEP-0027 extension and adding own extension of the protocol, our team achieved a full compatibility with all popular jabber-clients and support of a standard encryption system, which operates in a well-known PSI-client, as well as succeeded in organizing a fully automatic exchange of PGP public keys. This fact leads SafetyJabber client to a new level when there is no need to install an additional software (for an instance, GNUPG for PSI) for supporting OpenPGP encryption. Unfortunately, this extension is currently supported by SafetyJabber clients only.
We chose the agxXMPP open library for the complete support of XMPP protocol which is the most reliable and stable today.
Why do we need to send files via Sendspace?
It is necessary to mention that it is more reliable to send files via an independent source in an archive with a password consisted of 32 symbols automatically. To do that, you should push one button only. Resource www.sendspace.com allows to download files providing the highest reliability of the sent information.
Why do I need the lock mode when I am not near the computer?
The pay version of the program has a function, which we call “anticapture”. The sense of this function is very simple and it consists of the following points:
Here you can download the application and use it free of charge for your pleasure.
