I cannot decrypt files on OS X (10.6.8 and 10.8.2) which I have encrypted on Ubuntu (10.04) using ccrypt. As a similar problem, I have a password file created with KeePassX. I just cannot open it on OS X.
SHA256 checksums of encrypted files match, so they have not been corrupted during "transport." What could be causing this problem? Could it be, say, character encoding?
