Question on ext4 directory hashes in combination with file name encryption

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

if I read the ext4 code correctly, you pass encrypted filenames to ext4fs_dirhash().
These filenames are not encoded and therefore binary gibberish.
Isn't this a problem for the ext4 hash functions? My fear is that these hashes are optimized
for ASCII strings and produce more collisions when binary data is used as input.

Thanks,
//richard
