I started a thread a couple weeks ago looking for a good encryption App so I can send truly private text messages on my Droid. I got one suggestion for an encryption App that I couldn't find on the market. I found a web solution that I think won't really work for text messages (just too bloody cumbersome when I want to send a quick text message) but it is VERY cool for a free online service and I might use it for emails etc... socialock.net is the site. I tried using a "Password" that was a paragraph long and it worked. I would guess you could generate a pass phrase for your family or whoever that could be a poem or something and have encryption that is impossible to brute force...the equivalent of a 5000 bit key or something of that nature. I don't go on facebook or myspace which appears to be the intended audience for this service but...kind of nifty for some of the things I actually do.
