Putting SSH keys I've taken from Ubuntu I came over to Mac from Ubuntu. I've saved all SSH files I had in the .ssh folder in Ubuntu. There are three files


id_rsa
id_rsa.pub
known_hosts


Is it possible to reuse these files in Mac? If so, where do I put them?
You have to put them in the ~/.ssh/
OS X uses the same OpenSSH package as every other unix.
Make sure you have set correct permissions, or ssh will not accept your keys
