Today’s release of TextSecure is the final
step in the transition from a private SMS app to a private asynchronous IM app that does not depend on SMS/MMS.
Using the lessons we’ve learned from the SMS environment over the past four years, we’ve developed an open protocol
for asynchronous chat that enables private communication instantly with friends, private groups for real-time collaboration,
and the ability to quickly and seamlessly share media privately – all without depending on SMS.
