Keypairs

Secure, passwordless SSH access to your compute instances using public/private key cryptography.

What are Keypairs?

Keypairs consist of a public key and a private key. You upload the public key to redu.cloud, and keep the private key on your machine. When you launch an instance, you can associate a keypair so you can SSH into the VM without a password.

• Public key — stored in the platform and injected/authorized for your instance user (e.g., ubuntu)
• Private key — stays with you; never share it
• Fingerprint — a short identifier of a keypair for verification

When to use them

• Securely access Linux instances over SSH without passwords
• Automate deployments via CI/CD with scoped keys
• Rotate credentials by replacing keypairs periodically

Features

• Create/import an SSH public key as a keypair
• View keypair name and fingerprint in the dashboard
• Delete keypairs you no longer need
