![Hanna Reitz](/assets/img/avatar_default.png)
Our gnutls crypto backend (which is the default as of 8bd0931f6
)
supports neither twofish-128 nor the CTR mode. CBC and aes-128 are
supported by all of our backends (as far as I can tell), so use
aes-128-cbc in our iotests.
(We could also use e.g. aes-256-cbc, but the different key sizes would
lead to different key slot offsets and so change the reference output
more, which is why I went with aes-128.)
