             Summary: Allow OAuth2 refresh tokens to be hashed and irrecoverable 
                 Key: CXF-7819
                 URL: https://issues.apache.org/jira/browse/CXF-7819
             Project: CXF
          Issue Type: Wish
          Components: JAX-RS Security
    Affects Versions: 3.2.5
            Reporter: Thomas Iguchi


 

I want to store refresh tokens salted and hashed in my database since they appear to me pretty much like the equivalent of user passwords and I don't feel comfortable storing them in plain text.

I do not plan to delete refresh tokens unless requested by the user ("session termination") or after a long enough time of user inactivity. So in case my refresh token DB should get leaked I hope that the extracted data will be pretty much worthless.

 

However, the `OAuthDataProvider` interface has the following method:

 
{code:java}
/**
 * Return all refresh tokens associated with a given client
 * @param client the client
 * @param subject the user subject, can be null
 * @return list of refresh tokens
 * @throws OAuthServiceException
 */
List<RefreshToken> getRefreshTokens(Client client, UserSubject subject) throws OAuthServiceException;
{code}
 

It looks to me as if the framework is set up in a way so existing refresh tokens should be retrievable from the data store. This is a bit of a road block to me at the moment. I cannot recover the token string.

I used IntelliJ in order to trace usage of that method throughout my code base including CXF and cannot find a single caller (yet)...

I want to check back with you what the intended purpose behind that method is. Would it harm the (future) functionality of the CXF OAuth2 module if I would let that method return an empty list or just null, or maybe a list with blank token string properties?

Also, what is the idea behind that method? When would a client / user request all refresh tokens?

 

Thanks in advance!
