Encrypted files
|
|
|
|
|
---------------
|
|
|
|
|
|
|
|
|
|
- Each encrypted file has at least two components: the encrypted data file
|
|
|
|
|
('catfile'), and it's corresponding key file ('keyfile'). Shared files have an
|
|
|
|
|
additional key file ('share key'). The catfile contains the encrypted data
|
|
|
|
|
concatenated with delimiter text, followed by the initialisation vector ('IV'),
|
|
|
|
|
and padding. e.g.:
|
|
|
|
|
|
|
|
|
|
[encrypted data string][delimiter][IV][padding]
|
|
|
|
|
[anhAAjAmcGXqj1X9g==][00iv00][MSHU5N5gECP7aAg7][xx] (square braces added)

Notes
|
|
|
|
|
-----
|
|
|
|
|
|
|
|
|
|
- The user passphrase is required in order to set up or upgrade the app. New
|
|
|
|
|
keypair generation, and the re-encryption of legacy encrypted files requires
|
|
|
|
|
it. Therefore an appinfo/update.php script cannot be used, and upgrade logic
|
|
|
|
|
is handled in the login hook listener.
