Managing SSH Keys

Generating ED25519 SSH key pairs and uploading public keys to project workspaces.

Key-Based Authentication

Access to virtual machine instances in microsrv relies exclusively on asymmetric SSH key pairs. Password-based SSH logins are disabled by default across all images for security hardening.

Generating an ED25519 Key Pair

If you do not have an existing SSH key pair, generate a modern ED25519 key on your local machine:

microsrv:~$ ssh-keygen -t ed25519 -C "developer@example.com"

Your public key string is saved locally to ~/.ssh/id_ed25519.pub.

Adding Keys to Your Workspace

  1. Open Console -> SSH Keys.
  2. Click Add SSH Key.
  3. Provide a recognizable label and paste the public key string.
  4. Select your key during VM creation for automatic injection into the guest OS authorized_keys.
