Why is chmod 600 recommended on a public authorized_key??
When inserting (pasting) a public SSH key on a user's folder, within a Droplet, Im seeing a lot of people urge to
chmod 700 ~/.ssh
and then to
chmod 600 ~/.ssh/authorized_keys
But if i *chmod 600 ~/.ssh/authorized_keys* with my user then i am not able to login via ssh, i need to change it to *chmod 755 ~/.ssh/authorized_keys* in order to connect.
Which leads to my question: Why is so important to have a public key under chmod 600??
And why im not being able to connect with chmod 600 but only with chmod 755?
Thanks in advanced
