Publisher's description - Krypta 1.0
Krypta uses multiple/cascading encryption. Each file is encrypted using 256-bit encryption. Users may use 1 or 3 passwords to encrypt the file. A keyfile may also be used to maximize security, just make sure to store the keyfile in a safe place as the file cannot be decrypted without it. You may drag & drop files to the textbars or choose the files manually. Files should be decrypted in a separate directory from the original file as the decrypted file will share the exact same name. Unfortunately, the app can only encrypt/decrypt files once, then the app must be restarted to encrypt/decrypt files again.
