Using the Core CloudCypher Service
If you have purchased access to the Core CloudCypher service, you can send hashes directly from Core Impact to the service to attempt to crack them. Core Impact can be configured in Core CloudCypher Options to send them automatically or, if you want to do so manually, by selecting Tools > Submit Credentials to Core CloudCypher.... You can then enter the hosts that contain hashes.
