Simple Secure Secret Sharing

poof! is a simple, secure, time-constrained, one-time password sharing service, so you don't email/IM passwords to colleagues/friends/family.

There's a lot more technical detail on Github and the source code is really small, so as to be auditable.

What is this and why should I use/trust it?

Have a look at the FAQs and decide for yourself.
