The Dutchman sealed a deadline-day loan switch to Brighton and will link-up with Hughton for the second time in his career, having worked under him previously at Newcastle.
Krul has been out of the first-team picture with the Magpies over recent times and he spent last term on loan with Ajax and AZ Alkmaar.
The stopper believes Hughton was unfairly treated during his time at St James' Park and feels he will now prove his worth as Brighton look to avoid an immediate return to the Championship.
Krul said: "He built a togetherness in the team. When we were in the Premier League we had a great start. They kind of made a mistake there and I think Chris has proved that with what he has done at Brighton again.
"I am looking forward to being a part of that journey. He was definitely a massive part of the journey at Newcastle. I had a great time there. I would have liked to have finish on a positive, but I will always have a positive view on Newcastle.
"They've brought me everything I could wish for, so I could never have any regrets, 11 beautiful years, but Brighton is another family club and has a great set up to look ahead. The aim should be to stay up and it's got everything to stay there."
