Prisma Campaigns provides a secure SFTP server for you to upload and download data. This guide will walk you through setting up WS_FTP Professional to connect to our SFTP server using public key authentication.

Step 1: Generating an SSH Key Pair

To connect securely, you’ll need an SSH key pair: a private key that stays on your computer, and a public key that you will send to us.

On Windows (using WS_FTP Professional)

1. Open WS_FTP.
2. Go to Tools/Options.
3. In the Program Options window, select SSH/Client Keys.
4. Click Create… to open the SSH Client Key Pair Generation Wizard.
   
5. Choose RSA as the key type and set the key size to 2048 bits. Click Next.
6. Enter a name for your key (e.g., Prisma) and an optional passphrase for added security. Click Next.
   
7. Review the key summary and click Finish. The key generation process will begin.
   
8. Your new key will now appear in the Client Keys list.

On macOS or Linux

1. Open the Terminal application.
2. Run the following command:

   ssh-keygen -t rsa -b 2048
   

3. The command will prompt you to enter a file in which to save the key. You can press Enter to accept the default location (~/.ssh/id_rsa).
4. You will be asked to enter a passphrase. This is optional but highly recommended for security.
5. This will create two files: id_rsa (your private key) and id_rsa.pub (your public key).

Step 2: Exporting Your Public Key

You need to send your public key to the Prisma Campaigns support team so we can authorize your connection.

On Windows (using WS_FTP)

1. In the Program Options/SSH/Client Keys window, select the key you just created.
2. Click Export….
   
3. Save the public key file to a location you’ll remember. It’s best to use a descriptive name and the .pub extension (e.g., your_company_name.pub).
   

On macOS or Linux

1. If you used the default location, your public key is saved at ~/.ssh/id_rsa.pub.
2. You can view the key by running: cat ~/.ssh/id_rsa.pub.
3. Copy the entire output.

Step 3: Send Your Public Key to Support

Attach the .pub file (or paste the copied key) and send it to your Prisma Campaigns support contact through a secure, agreed-upon channel. We will install the key on the SFTP server. Please wait for confirmation that your key has been installed before attempting to connect.

Step 4: Configuring the SFTP Connection in WS_FTP

1. In WS_FTP, click Connections/New Connection.
2. Enter a Site Name (e.g., Prisma Campaigns SFTP).
3. For Connection Type, select SFTP/SSH.
4. For Server Address, enter sftp.prismacampaigns.com.
5. Enter the User ID provided to you by Prisma Campaigns.
6. In the left pane, go to SSH.
7. For the authentication method, check Public Key.
8. From the SSH keypair dropdown, select the key you created earlier (e.g., Prisma).
   
9. Click OK to save the site configuration.

Step 5: Connecting to the Server

1. From the main WS_FTP window, select the site you just configured from the Connections dropdown and click Connect.
2. The first time you connect, you will be presented with an Untrusted SSH Server Key warning. This is normal. Verify the key details if provided by support and click Trust this key.
   
3. If the connection is successful, you will see your local files on the left and the remote directories on the Prisma Campaigns SFTP server on the right.
