2015-12-19Increase GCM IV size from 96 to 128 bitsJakob Unterwurzacher
This pushes back the birthday bound for collisions to make it virtually irrelevant.
2015-11-15CipherSizeToPlainSize: Handle illegal statesJakob Unterwurzacher
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)
2015-11-01Refactor 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.
