notary key list truncates GUNs

[rhopfer]

The command notary key list truncates the GUNs without the possibility of displaying them as a whole. If you have several domains that end in the same way, you can't differentiate between them, e.g. testing.example-domain.com and production.example-domain.com.

$ notary key list
