# SSH Client

## SSH to a Linux server using RSA key

### Convert the RSA key from Windows

Download and install [Putty](https://www.chiark.greenend.org.uk/~sgtatham/putty/latest.html).

Putty comes with a tool called PuttyGen, which is used to convert RSA keys to Windows format.

Open PuttyGen, Click on **Conversions** menu and select **Import Key**.

Browse to the folder that contains the .pem

When finished, click the 'Save private key' button to save it into a **.ppk** file.

{% hint style="info" %}
If you need to revert the conversion from Linux you can `apt install putty-tools` and then `puttygen server.ppk -O private-openssh -o server.pem`
{% endhint %}

#### SSH connect

Open PuTTY and navigate to 'Connection > SSH > Auth'.

Click the Browse button near the 'Private key file for authentication' field.

Select the **.ppk** file you generated and then click open.

Navigate to the 'Session' category and enter the IP Address of your server in the 'Host Name' field and connect.
