title: Keystore password? Huh?
body: <p>I am attempting to create a GCP Signed URL using instructions <a href="https://cloud.google.com/storage/docs/access-control/signing-urls-with-helpers" rel="nofollow noreferrer">here</a>. When I run the gsutil command to create my signed-url I am immediately prompted to enter my "Keystore password". So this:</p>
  
  <pre><code>gsutil signurl -d 10m my-private-key.json gs://my-storage-bucket/index.html
  </code></pre>
  
  <p>results in this:</p>
  
  <pre><code>Keystore password: [I enter a wrong password]
  Encountered an error while refreshing access token. If you are using a service account,
  please verify that the gs_service_key_file field in your config file(s), /Users/my-user/.boto, /Users/my-user/.config/gcloud/legacy_credentials/my-gcp-user-email/.boto, is correct.
  </code></pre>
  
  <p>To be frank I haven't the slightest what my keystore password is or even what keystore it is talking about. Is it a local Mac keystore? Is it a GCP keystore? Something else?  </p>
  
  <p>Any clues as to what keystore is being referenced or even how I might go about changing the password to something else are appreciated.</p>
