Protecting your personal and confidential information since 2009, Krypton is the first, simplest and most reliable App on the iOS Store to strongly encrypt entire documents and folders. Now also available on the Mac App Store. Your stuff is secure from prying eyes no matter where you are in the world.

Because the unit of encryption is an entire document or folder, Krypton is not a password manager in the traditional sense, although you can maintain a document of all your passwords that you encrypt between uses. Krypton can encrypt any type of document, including but not limited to:

•Pictures from your photo album.
•Movies from your camera roll.
•Email messages from your mailbox.
•Songs, PDFs, movies, Zip files, word processing documents, text files, images, program source code or any other object that you can download over the network or from your personal web server.
•Anything on the iOS pasteboard.
•Any document other Apps are willing to Share, such as Pages, Numbers and Keynote.
•Dropbox files for easy cloud synchronization.

Krypton uses strong encryption (256-bit AES, CBC, PKCS7, PBKDF2, SHA-512) on each item; this has several ramifications:

•If your passcode is strong enough to withstand a brute force attack, no one is going to see your stuff.
•If you forget your passcode, no one can recover your stuff for you! But only that one document is lost, not your entire collection of items.
•Your stuff is secure even if your iDevice or Mac is stolen, or Dropbox account is compromised.

And if you find a problem with Krypton, please email a report to, which guarantees that the bug gets fixed, fast. It's time better spent than writing a 1-star review that may not get read until months later ... pent up anger is bad for your health. Thus far, not a single person who wrote a bad review has ever reported their problem.
