Converting SSH keys for WinSCP

If you want to use WinSCP as an SFTP client to connect to your Acquia Cloud servers, you may need to convert your SSH key into a format compatible with WinSCP. You can use PuTTYgen to convert your key into the .ppk format required by WinSCP.

PuTTYgen is included in the WinSCP installation package.

To convert a key into the .ppk format using PuTTYgen:

  1. Start PuTTYgen, and in the Conversions menu, click Import key.

    Select Conversions > Import key

  2. In the Load private key window, browse to your SSH private key, select it, and then click Open. Your SSH private key is probably located in Users\[user_name]\.ssh.

    Select your private key and click Open

  3. Enter the passphrase associated with the private key. Note that the key fingerprint confirms the number of bits is 4096.

    Enter the key's passphrase

  4. In the File menu, click Save private key to save the key in .ppk format.

Use this .ppk file as your key when you use WinSCP.

For more information, see the PuTTYgen documentation, including this note about key formats.
