Locker

Locker is a free, open-source application for composing and storing encrypted notes.

Whether simply protecting a list of passwords or credit card numbers, or guarding your secret manifesto, Locker allows you to encrypt and lock individual notes with a unique passphrase. Using the same algorithm approved by the US Government to protect Top Secret Classified Information, Locker prevents unauthorized access to your notes completely independent of any device locking mechanisms. Moreover, it accomplishes this in style, providing a satisfying graphic effect.

Locker currently requires zero permissions, and doesn’t display advertisements or perform data collection. Relatively minimal in terms of features, a user can compose, edit, save, and delete notes, and edit note names and passphrases. Note size is currently limited to 200 lines. Locker uses a key extension algorithm to transform a passphrase into a 256 Bit Key and then encrypts the note using AES (Advanced Encryption Standard).
