----------------------------------
> s3RevokedStsTokenTable key is the full token str

> Key: HDDS-16110
> URL: https://issues.apache.org/jira/browse/HDDS-16110
> Project: Apache Ozone
> Issue Type: Sub-task
> Components: S3
> Reporter: István Fajth
> Assignee: Fabian Morgan
> Priority: Major
>
> During gathering a deeper understanding on what can be a common ground
> between the Custos design that is being discussed over
> [GitHub|https://github.com/apache/ozone/pull/10742] I found a potential
> operational problem with STS token revocation. [~fmorgan] can you please look
> into this?
> Based on the revocation check code path, it seems for me that the full token
> str (which is essentially the client's secret) is being used as the key in
> the revocation table.
> In
> [S3SecurityUtil|https://github.com/apache/ozone/blob/HDDS-13323-sts/hadoop-ozone/ozone-manager/src/main/java/org/apache/hadoop/ozone/security/S3SecurityUtil.java#L77]
> the check goes by the full token string extraced from the request.
> This means that the admins would need to revoke a token based on the actual
> token content which if my understanding is correct should be kept secret
> between the client and the server morover which we do not log anywhere for
> the same reason.
> So this means that essentially the only way to revoke a token is by knowing
> the token, and that should be known only by the client who asked for the
> token.
> May we use some id that we already have generated for the token that is
> present in the audit logs where a rouge access with a token may be identified?
