Safeguarding your personal and confidential information since 2009, Krypton is a privacy tool that uses strong encryption to securely protect data resident on your iOS and macOS devices. Krypton is not a password manager: it encrypts and decrypts entire folders and documents (text, spreadsheets, images, audio and video, recipes, emails, anything).

Terminology:

• Plaintext refers to any item, whether a text file, image, Word or Pages document, spreadsheet, HTML or sound file, etc., in its normal format.

• Ciphertext refers to a plaintext item that has been encrypted, and is thus unrecognizable.

• A passcode is a string of letters, numbers and special characters used as a key during encryption and decryption. The only way to decrypt a Krypton item is by knowing the passcode used to encrypt it.

Metaphorically, Krypton keeps your ciphertext items in a special vault, with each item contained in its own deposit box — to gain access to a ciphertext item the vault must be open, and to gain access to its plaintext contents the passcode key must be used to unlock the deposit box. For iOS the vault may be open or closed, while on macOS the vault opens upon Log In.
