SSH Keys: A Simple Guide to Secure Remote Access
Secure Shell (SSH) keys are a widely used method for secure authentication between systems, especially in managing remote servers. Using SSH keys eliminates the need for password-based logins, enhancing both security and convenience. Below is a guide on how to generate two types of SSH keys: RSA and ED25519. Generating an RSA Key To create an RSA key with 4096-bit encryption, use the following command: ssh-keygen -o -t rsa -b 4096 -C "your_username" -o: Use the new OpenSSH format for private keys. -t rsa: Specifies the RSA key type. -b 4096: Sets the key length to 4096 bits for added security. -C “your_username”: Adds a label (comment) to the key, typically your email or username. ...
