Stuck on bandit16 level at overthewire

I am trying to solve the CTF challenges at overthewire and have completed up to 16 levels

To get from level 16 to 17 you have to send the password of the current level to the port supporting SSL on localhost after submitting the password an ssh private key is given to log to the next level

I have done up to here and have successfully got the ssh key save it in a text file changed permission to 600 but whenever I am trying to use this key to log in to the next level I am prompted to give the passphrase for the key I have been stuck here for a long time how I can provide the passphrase since while creating the key there was nothing to set the passphrase

I almost lost it with this one, but just logged in, had the same problem as the author, tried changing it to chmod 400 then 600 still had the same problem. What worked was copying the the key from the comment above, I suspect the "<" symbol in front of every line when copying from the terminal was somehow interfering with this.

When you send the correct password, you should get the following key:

You should copy this to your local computer, and save it as a file called bandit.key (name doesn't really matter). Then you should chmod 600 bandit.key, then ssh with the keyfile with the command:

ssh -i bandit.key [email protected] -p 2220

Which should log you in.
