SSH Key Permissions

Proper file permissions help keep your SSH keys secure. On most systems, you can set permissions using chmod:

chmod 700 ~/.ssh
chmod 600 ~/.ssh/id_rsa
chmod 644 ~/.ssh/id_rsa.pub

~/.ssh directory should be readable, writable and executable only by you (700).
Your private key (e.g. id_rsa) should be readable and writable only by you (600).
The public key can be world-readable (644).
