Design ------ * Authenticated encryption of file contents using AES-GCM-128 - * 96 bit nonce that starts from a random value and counts up + * Because GCM handles blocks of arbitrary size, there is no special handling for the last file block + * 4096 byte blocks per default + * 28 bytes of overhead per block (16 bytes auth tag, 12 byte nonce) * uses openssl through [spacemonkeygo/openssl](https://github.com/spacemonkeygo/openssl) for a 3x speedup compared to `crypto/cipher` -* AES-CBC filename encryption +* Per-write unique 96 bit nonces + * starts from a random value (generated at mount time) and counts up +* Flename encryption using AES-CBC-128 + * Padded to 16-byte blocks acc. to [RFC5652 section 6.3](https://tools.ietf.org/html/rfc5652#section-6.3) + * base64 encoded acc. to [RFC4648 section 5](https://tools.ietf.org/html/rfc4648#section-5) Current Status -------------- -* Work in progress -* Key is set to static all-zero -* Not ready for anything but testing and debugging +Not ready for anything but testing and debugging + +* File and directory creation and deletion works +* Thread-safe nonce generation works +* Filename and content encryption works + * Key is set to static all-zero +* Reading and writing works +* Streaming performance is already reasonable + * But we should be able to get another 50% speedup +* Symlinks and hard links not yet implemented +* Memory usage is insane Install ------- |
