2015-11-01Refactor ciphertext <-> plaintext offset translation functionsJakob Unterwurzacher
Move all the intelligence into the new file address_translation.go. That the calculations were spread out too much became apparent when adding the file header. This should make the code much easier to modify in the future.
2015-11-01Add file header (on-disk-format change)Jakob Unterwurzacher
Format: [ "Version" uint16 big endian ] [ "Id" 16 random bytes ] Quoting SECURITY.md: * Every file has a header that contains a 16-byte random *file id* * Each block uses the file id and its block number as GCM *authentication data* * This means the position of the blocks is protected as well. The blocks can not be reordered or copied between different files without causing an decryption error.

...also adapt the cryptfs tests for 256 bit long keys

2015-10-04intraBlock: Rename Offset to SkipJakob Unterwurzacher
"Offset" is unclear whether it is an offset from the start of file or start of block. "Skip" seems much better.
2015-10-04Add BlockNoPlainOff() and BlockNoCipherOff() + testJakob Unterwurzacher
Also, fix key, it is now []byte, not [16]byte
