1. Does it cause a security problem to share an SSH public key with your friends?
Which authentication for SSH login is more secure?
When generating the SSH public/private key pair, is it secure to use empty passphrase?
| Info: | Verify the fingerprint of remote host, before the first login. User the SSH public key authentication for login. Never use an empty passphrase for the SSH keys. Use strong passphrase to generate the SSH keys. Keep your private SSH key as top secret. Create, configure and use different SSH keys for different remote hosts. If no X11 application is required, disable X11 forwarding. Otherwise, only enable the untrusted X11 forwarding. |
| Warning: | lots of tips are given, no warning. |
