Feature request: Easy wrapping of existing secrets for sharing

[schulzh]

Feature request:

Is this a front-end feature or backend?
Front-end (I think).

Description of feature:
One feature which we miss after switching from https://github.com/djenriquez/vault-ui to Goldfish is the ability to wrap secrets easily without copying them around.
While viewing a secret, you can click "Wrap Secret", choose a time and get a one-time token and url with which to get the secrets again. This makes it very easy to share secrets securely with people who do not use vault frequently and/or do not have access to the secrets otherwise.

Are you able to submit a pull request for this feature?
No
