2015-12-10Add missing PlaintextNames checks in OpenDir, Mkdir, Rmdir, initDirJakob Unterwurzacher
Plaintextnames support has bitrotted during the DirIV additions, this needs test cases. Will be added in a future patch. Fixes issue #9.
2015-12-08Add EME filename encryption & enable it by defaultJakob Unterwurzacher
2015-12-06Fix rename, was broken broken by DirIV introductionJakob Unterwurzacher
As it was, CIPHERDIR was prepended twice, causing every rename to fail with ENOENT.
2015-11-29Run go fmtJakob Unterwurzacher
2015-11-29Add single-element cache for DirIV lookupJakob Unterwurzacher
Another 3x performance boost for applications that walk the directory tree. Excerpt from performance.txt: VERSION UNTAR LS RM v0.4 48 1.5 5 v0.5-rc1 56 7 19 v0.5-rc1-1 54 4.1 9 v0.5-rc1-2 45 1.7 3.4 <---- THIS VERSION
2015-11-29OpenDir performance: Read DirIV once and reuse it for all namesJakob Unterwurzacher
Formerly, we called decryptPath for every name. That resulted in a directory walk that reads in all diriv files on the way. Massive improvement for RM and LS (check performance.txt for details) VERSION UNTAR RM LS v0.4 48 5 1.5 v0.5-rc1 56 19 7 v0.5-rc1-1 54 9 4.1 <---- THIS VERSION
2015-11-28diriv: also support old CBC symlinkJakob Unterwurzacher
2015-11-28diriv: fix Symlink() and Readlink()Jakob Unterwurzacher
Both were missing adaptions for diriv usage resulting in broken functionality
2015-11-28diriv: fix readdirJakob Unterwurzacher
It decrypted all file names using the root directory iv
2015-11-28diriv: use "DirIV" flag to discern and support mounting old filesystemsJakob Unterwurzacher

2015-11-27diriv: Move WriteDirIV() to cryptfs; add locking to Mkdir, RmdirJakob Unterwurzacher
2015-11-27diriv: Convert filename encryption users to dirivJakob Unterwurzacher
2015-11-25diriv: Transactionally delete gocryptfs.diriv in RmdirJakob Unterwurzacher
2015-11-25diriv: Create gocryptfs.diriv in every directoryJakob Unterwurzacher
2015-11-14Run go fmt and go vetJakob Unterwurzacher
2015-11-09Add "-q" (quiet) flagJakob Unterwurzacher
2015-11-03Centralize path filter decision in CryptFS.IsFiltered()Jakob Unterwurzacher
2015-11-03Implement PlainTextNames modeJakob Unterwurzacher
Also, forbid access to "gocryptfs.conf" in the root dir.
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.

2015-09-13Encrypt key with scrypt-hashed passwordJakob Unterwurzacher
2015-09-09Fix File.GettAttr() size reportingJakob Unterwurzacher
The too-large reported value broke mmap (applications saw appended zero bytes) Also * Add locking for all fd operations * Add "--debug" command line switch

2015-09-08Add pathfs frontend (uses go-fuse instead of bazil-fuse), part IJakob Unterwurzacher
Currently fails main_test.go, will be fixed in part II
