Krypton is a privacy tool that uses strong encryption (256-bit AES, CBC, HMAC-SHA256) to securely protect personal and confidential information resident on your computer. Krypton is not a password manager: it encrypts and decrypts entire documents (text, spreadsheets, images, recipes, emails, anything).

Krypton 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 words and characters used
