# Convert PEM Keys to PPK for Windows SSH Clients

**Last reviewed:** September 21, 2026

Use this page when an administrator needs to connect to an AIQ host from a Windows SSH client that requires PuTTY private key format.

## When to use this guidance

- You have an approved PEM private key for the AIQ host.
- Your Windows SSH client requires a PPK key.
- The key will be stored and protected according to your security policy.

## Recommended approach

1. Install or use the approved PuTTYgen version from your organization’s software catalog.
2. Open PuTTYgen and load the PEM private key.
3. Add or confirm a passphrase if policy requires it.
4. Save the converted PPK file in a protected location.
5. Test access with the target host and remove any unnecessary duplicate key files.

**Note:** Private keys are sensitive credentials. Do not upload them to documentation, tickets, or shared drives unless explicitly approved by security policy.
