QRTalk is a mobile messaging platform designed to defend information exchange from
unauthorized access, disclosure, inspection or recording.
QRTalk is private, secure,
temporary and anonymous.
★ Private: everything is in your hands.
QRTalk consists of a server
and a mobile app.
You can run your own server, or connect to a server run by someone else
you trust.
You are in control of data storage, physical server access and service
life-span.
★ Secure: strong end-to-end encryption.
All exchanged messages are encrypted end-to-end on your device.
Encryption is done using a serial combination of symmetric-key and
public-key cryptography, much like PGP does.
A new random symmetric key is generated for each message and plain-text
is encrypted using generated key. Symmetric key is then encrypted using
recipient's public key and sent to server for delivery along with encrypted
message.
Asymmetric key pairs are generated on your device.
Public key fingerprints can be exchanged to double-check the identity of
other users (recipient certification). Once you verify a public key you are
guaranteed that nobody but the verified user will ever be able to read your
messages.
You can sign messages with your own private key (sender certification).
Message forging (using stolen public keys) and man-in-the-middle attacks are
totally impossible when exchanging signed messages.
★ Temporary: user selected time-to-live.
All exchanged messages are tagged with a user selected time-to-live.
When time-to-live expires messages are deleted from server, from your
device and from all destination devices.
★ Anonymous: no personal info.
QRTalk uses anonymous
random IDs to identify users and groups.
User IDs are used to route messages from sender to recipient devices.
The only information stored on server is anonymous user IDs, group IDs
and public keys. Avatar pictures and nicknames are stored on your device only.
You can install QRTalk for free and start
sending and receiving messages immediately. Follow in-app instructions or visit
out web site to obtain activation codes.
