Setup your SSH Keys

Create, import, download, and manage SSH keys in HexGrid Cloud. This guide covers generating a key in the dashboard or on your computer, importing an existing public key, and managing saved keys.

What is an SSH key?

An SSH key securely proves your identity when you connect to a remote computer, such as a cloud GPU instance. It has two parts: a public key you can add to HexGrid Cloud, and a private key that must stay secret on your device.

Never upload, paste, email, or share your private key. HexGrid Cloud needs only your public key when importing a key from your computer.

Open HexGrid Cloud

Visit hexgrid.cloud and select Get Started, or open the sign-up page.

Open Access Keys

In the left sidebar, find Compute and select Access Keys. Choose the SSH Keys tab. You can generate a new key in HexGrid Cloud or import an existing public key.

Add an SSH key

Choose one of the following options.

A: Generate in HexGrid Cloud
B: Generate on your computer
C: Import an existing key

Click Generate SSH Key.
A key is generated automatically; edit its name if desired.
Click Download Private Key and save it securely. The private key may only be available for download at this point.
Use Download public key if you need a copy of the public key.
Close the dialog. Your key appears in the list.

Download and safely store the private key immediately. Do not share it or upload it to HexGrid Cloud.

Open Terminal on macOS/Linux, or Git Bash or PowerShell/Windows Terminal on Windows. Run:

ssh-keygen -t ed25519 -C "your-email@example.com"

Follow the prompts. Press Enter to accept the default file location, or enter a path you will remember. You can set a passphrase for extra protection.The usual files are:

File	Type
`~/.ssh/id_ed25519`	Private key
`~/.ssh/id_ed25519.pub`	Public key

On Windows, look in your user profile’s .ssh folder.Copy the public key

cat ~/.ssh/id_ed25519.pub

Get-Content $env:USERPROFILE\.ssh\id_ed25519.pub

Copy the complete line beginning with ssh-ed25519. If you chose another filename, use that filename instead. Then import it using option C.

Open Compute → Access Keys → SSH Keys.
Click Import SSH Key.
Enter a recognizable name, such as “Personal laptop.”
Open your public-key file (ending in .pub) and copy its entire contents.
Paste it into SSH public key. It commonly begins with ssh-ed25519 or ssh-rsa.
Click Create key. The key should appear in the list.

Never paste the private key into this form. The public key ends in .pub; the private key does not.

Manage saved keys

The SSH Keys page shows saved keys. You can copy the public key or delete a key you no longer need.

Before deleting a key, check whether any deployment or machine depends on it.
