Bandit level 25 requires us to get a shell in order to get access to the next level.
So, let’s start by logging into the machine
ssh bandit25@bandit.labs.overthewire.org -p 2220
with the password we got from the previous level
uNG9O58gUE7snukf3bvZ0rxhtnjzSGzG
now, let’s start by listing the files in the home directory
and we can see that there’s an ssh key for the next user, so let’s print that key, save it in a local file on our machine then connect to bandit 26 with it.
cat bandit26.sshkey
you would get the following value
-----BEGIN RSA PRIVATE KEY-----

Now, let’s create a new file and save the above in it.
then we need to change the permission to 600 in order to add the key
chmod 600 bandit26.key
then let’s add the key to ours
ssh-add bandit26.key
and that should be it for the current level, you can continue to the next level with that key.
