Kioshi.6597:

Is it possible to check the permissions enabled on a given key? (A quick way at least. I could of course manually check them). I would like to use this to check if the user set up their key correctly.

This is more or less what I do. Pull the tokeninfo, and store the permissions in a list.

Compare against that and raise an exception if it’s missing.

Mind you the wiki is slightly outdated. It does return ALL the permissions as expected.
