Default Authorizer implementation that allows all signature requests.
Default BucketLister implementation that lists all objects in the configured bucket.
Default TransactionIdProvider implementation that generated random-based UUIDs using the java.util.UUID Generator.
Default UrlSigner implementation that signs all requests, putting all objects in a specific S3 bucket and limiting the signature time to a configurable time period.
Uses an externally provided UUID obtained from an application property externalUUID when this is available.
UrlSigner implementation that extends the DefaultUrlSigner class to perform some additional work - speficically this class renames the S3 objects keys based on the transaction ID.
Implementations of interfaces used by the Gatekeeper servlet to do its work - these implementation classes can be used as-is, but it is more likely they will be used as a starting-point for Service Providers who will extend them to perform exactly as needed in their authorization scenarios.
