Thanks for the quick reply Heikki,

See, for example,

What's available now is supported for encrypted secrets using a fixed
key. What will follow is method to specify the encryption key so that it
does not need to be static but can be set, for example, when the process
starts up.

There are some Radiator users that require that this type of information
is not stored in clear text, as we discussed on this list earlier :),
and what we now have in Radiator is the foundation for this.

To summarise: Using a non-cleartext secret or TACACSC+ key is now
possible but managing the encryption keys will be enhanced in the future
