Problems with the ssh key format

I am solving a box on another resource and got a ssh key
But when connecting to ssh, it gives an error
I think the key was changed here specially, but I can’t find out what’s wrong

you have to prepare the key, so that you can use it as a key.
chmod 700 id_rsa should solve your issue

Yes, I know about it. I used chmod 700 and chmod 600 still the same error

hmmm, and in the same directory as you write your statemant ?


This isn’t ‘over the wire’ is it by any chance? They changed all the passwords recently.
