signatory to display the public key (not hash) of a given cloud kms

[nicolasochem]

I am writing a tutorial on how to use signatory + consensus key + google KMS and I am hitting the following problem:

[venv] nochem@peck ~/workspace/sandbox/gcp-kms-signatory $ ./signatory-cli  list -c signatory.yaml --base-dir .

  Could not parse input.         

I can solve it by signing a reveal operation and looking at the result on-chain but it's unnecessary; can we modify signatory to display the pubkey in addition to the hash? many thanks.

regarding "no public_key alias" from octez-client, possible you still need to import into octez-client private keys, the Signatory URI, and use that alias going forward
https://signatory.io/docs/cli#configuring-octez-client-to-use-signatory-for-remote-signing

I can understand wanting to get the public key value from signatory-cli before activating it, makes sense. one way to get the public key from Signatory is to make the key Active by configuring it in the tezos section of signatory.yaml. once active, the key's URI can be queried for the public key:
% curl localhost:6732/keys/tz1VSUr8wwNhLAzempoch5d6hLRiTh8Cjcjb
{"public_key":"edpkvGfYw3LyB1UcCahKQk4rF2tvbMUk8GFiTuMjL75uGXrpvKXhjn"}

Yes, I figured this shortly after writing this ticket, and it works. Still it doesn't hurt to display it, but feel free to close otherwise.
