See: https://steemit.com/eos/@nadejde/eos-key-generator (Nadejde recommending ppl to use his alternative key-generator)!
For those who have used an alternative EOS key generator, I would personally advise you to go re-register your address using the one directly from the EOS portal instead. Just go through the exact same procedure as you did but with the new address.
It just seem really dodgy to me that someone is recommending an alternative generator when one is already available on the actual portal itself!
