[cont'd] created on each smartphone and the public key is sent to the recipient when first contacted. In return, the recipient sends his public key to the sender. Using RSA algorithm to exchange the AES key avoids third parties having to know the secret key necessary for decrypting a message. The app doesn't interfere with any of your regular yet unsecure SMS applications and encrypts messages end-to-end, so no plain text message will ever be leaving your device. SQURE encrypts messages on the terminal device (end-to-end) so messages are always sent encrypted. As a result, nobody can intercept and read them.
I could get really technical here and list the vast amount of complicated data needed to explain exactly how SQURE works...but I won't. The pure fact is, the app is totally secure and all your messages - and your contact list - will remain confidential. All data stored in the terminal device is always stored encrypted. There's no registration required and the app is completely free - all you have to do is to download SQURE and start the app and you are in business. The NSA might still be able to monitor your Internet use but not even they can 'listen in' on your private communications when you use SQURE.
