Resolution: Fixed
> Change RemoteAuthProvider to use a hash of the Key used for Caching
> -------------------------------------------------------------------

> Key: KNOX-3101
> URL: https://issues.apache.org/jira/browse/KNOX-3101
> Project: Apache Knox
> Issue Type: Improvement
> Components: Server
> Reporter: Larry McCay

> Time Spent: 20m

> The initial implementation of RemoteAuthProvider caches authenticated
> Subjects locally based on the header that contained the credentials. While
> the cache is designed to provide only a few mins of caching, it is less than
> ideal to use the credentials as keys. This needs to be strengthened to use a
> hash as to not inadvertently risk leaking the credentials.
> This will require some overhead involved in the hashing so we may need to
> find something else but we shouldn't use the credentials themselves. We would
> normally have to do a hash for implementing authentication for things like
> RDMS or LDAP based passwords, etc.
