Key issues with the latest data dump

I just got a new mac laptop. I did a file transfer from my old laptop to my new one. Instead of starting from scratch and following the machine setup instructions from my company.

Recently, I just downloaded a new data dump. Now I am receiving a padding check failed error. I was told this could be because my keys don’t match the keys that the data was made from.

Should I create a new set ssh keys for my environment? I have never done it before so I am a bit nervous. But a more experienced co-worker that just started is having no problems.
