SMS Salama is mobile phone Java application with which you can send and receive encrypted SMS.

Normally, SMS are transmitted as plain text, so any one with access to your operator’s network may be able to obtain the contents of your message. Some operators may even allow their customer service personnel to look into your messages.

With SMS Salama you are sure your message will only be seen by your intended recipient as long as the password used to encrypt it is a well kept secret between you two (and needless to say, it is strong enough).

Your SMS will be encrypted as it leaves your phone, ensuring that it can only be open by the password used to encrypt it when it reached its destination.
