WellRed Apps launched its DropKey file encryption app for Mac last month, but realized that there's one issue with gaining widespread acceptance -- it takes two to tango, and it takes two copies of DropKey (one each for sender and recipient) to send files securely. The company had been giving away one free license with each purchase of DropKey, but is going all-out through Sunday by making the app completely free.
DropKey pairs 2048-bit keys with 256-bit encryption for incredible security. The app, which requires a Mac running OS X 10.7 or later, is integrated with Address Book and makes encryption drop-dead simple.
When you launch DropKey for the first time, it generates your public and private encryption keys. You can email your public key to a trusted recipient from the app, which adds the key information to your address book card on the recipient's Mac. Prior to that time, a shared password is required; after the keys have been shared, you no longer need the password.
DropKey is a useful app if you need to send encrypted information to co-workers on a regular basis, and there's no better time than now to download a copy for free from the Mac App Store.
