i was talking about changing the encryption cipher, not the
passphrase. i
found aes128 faster than twofish128 on my machine, so i wanted to
change
it. the passphrase of the gpg key was not changed here.
Ah, yes -- well, do not *ever* re-encrypt in-place (from/to the same
data volume) with dd! I suppose it would work, as loop-AES is a block-
level cipher, but I always move from one *disk* device to another
when modifying the underlying encryption scheme.
