Comment 2 for bug 919049

Thanks for the bug report. I think you're correct on the ECRYPTFS_SIG_SIZE_HEX / KEYBYTES inconsistency. I'll get that fixed.

As for making the cipher and key size configurable, I won't be doing this for mount.ecryptfs_private. If you have a strong opinion and a need to modify these, then you should use mount -t ecryptfs -o options, and not the ecryptfs-setup-private helpers. The goal of the private helpers is to assist less technical Ubuntu users setup encryption in a way that they don't need to care about the defaults and in a manner that we can support them consistently. Sorry.

Thanks!
Dustin
