Using PGP (or gpg) is powerful and secure when you can use it. In all the years I’ve kept encryption keys in my stable, hardly anyone will use them for encrypted messages or files.

Dropkey is software that intends to make that simpler. It’s free until Sunday. 

We all send a lot of files. Whether it’s in Mail, with iChat, or even sharing them in Dropbox, files are still a huge part of our daily lives. Sadly, we haven’t had an easy way to make sure they can only be opened by the people they were intended for.
