Jane helped Toa by generating new - and safe - private and public keys, and the service was good to go again.

But, all good things must come to an end. New guidelines from GroundSpeak required the reviewers to do additional manual checks before accepting to reserve cache coordinates and so the automated service was discontinued. 

The secure keys that Jane created for the service were:
