After the introduction of the functional program encrypt messages using OTR messenger users SJ can not worry about the safety and privacy of correspondence.
For message encryption algorithm SJ uses OpenPGP encryption and OTR, which in the first case provides security by using a pair of keys, and the second – through the exchange of fingerprints , or keyword ( passwords , etc.). The user creates a key pair or imports into the program that provides complete anonymity of the user . Supported size keys – up to 4096 bytes. This key will ensure full confidentiality of correspondence .
To encode the history of the chat program uses an algorithm AES. Get access to the correspondence will not be possible without the password from the PGP-key.
In addition to increasing the level of confidentiality of personal correspondence, SJ Software Development Group presented a secure way to transfer files in archives. The program has a function of transmitting «One click to send», through which the user can send the zipped file in a single click with a password of 32 characters.
By optimizing application clients receive maximum safety when dealing in all messengers, using standard XMPP protocol and Oskar. SJ client is compatible with all popular instant messaging services: ICQ, Psi, Miranda and others. Communication Privacy ensured also on the social networks Facebook, GTalk, VK, Ya-line, etc.
To encrypt messages when communicating in social networks, you must add the application profile SJ, specifying username for social networks instead of jabber ID. External users will see the message in the format “message encrypted” and “Message decrypted.” Correspondence to encrypt application ios jabber SJ must be installed at both of them.
Importantly, the coding system and data encryption PGP is the most robust, and has virtually no chance of breaking. Thus, the creator of Philip Zimmermann noted that even the experts do not have the FBI encryption methods such correspondence.
The site Companies SJ Software Development Group can download jabber , and also to read about all innovations, Nuance use and advantages messenger.
