Gems in chef-client version

How can I know that the particular release of chef-client is having these many gems?

Suppose I need to check whether version 13.8.5 is having chef-vault gem or not ? I sthere any link to check so

I might not be answering your question here, but chef-vault is not included in the chef-client install. If you look at the following link under the ‘Using chef-vault in recipes’ section, it explains how to use it in recipies.
