Jakob Unterwurzacher	296bdf3af2	CipherSizeToPlainSize: Handle illegal states ... A file never gets a cipherSize <= HEADER_LEN in normal operation. However, this can happen if header write it interrupted or the underlying filesystem does not support fallocate. Noticed while trying to store a CIPHERDIR in another gocryptfs mount (gocryptfs does not support fallocate)	2015-11-15 14:15:21 +01:00
Jakob Unterwurzacher	902babdf22	Refactor ciphertext <-> plaintext offset translation functions ... 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.	2015-11-01 12:11:36 +01:00
