-====== SSH - Blacklist a public key ======
-You could remove the keys from each respective **.ssh/authorized_keys** file, but to do it on a server-wide basis.
-Look into the **RevokedKeys** configuration option for the sshd.  See man sshd_config.
-Remove john@server1.sharewiz.net from ~/.ssh/authorized_keys and lock the user account too:
-<code bash>
-cd /home/john
-sed -i '/ john@server1.sharewiz.net$/d' ~/.ssh/authorized_keys
-passwd -l john
