IP Whitelisting and Key Generation

We’ll need you to provide the IP Address (or subnet) from which you will be sending files, so we can whitelist and allow connection attempts from you. Next, we’ll ask you to create a Public/Private key pair, and provide the Public Key to us.  We’ll then be able to authorize your key, and you will be able to use your Private Key as your password to connect.

During implementation, you'll complete these steps via Trello. If you need to update your IP address range or key, contact us at [e-mail].

Please follow the steps below to generate your public and private keys.

Key Generation:

• Windows Key Generation
• Linux Key Generation

Note: Do NOT share your private key with anyone! If you believe your private key has been compromised, please regenerate your public and private keys immediately and send us your updated public key.

Windows Key Generation

We highly recommend using the PuTTY SSH suite of software for its ease of installation and use. You can download either the entire suite, or just the programs needed (PSCP, PuTTY gen, and PuTTY) for free from the following URL:

http://www.chiark.greenend.org.uk/~sgtatham/putty/.

1. Open the “PuTTYgen” program
2. Ensure that key type is set to "EdDSA" and the curve “ed25519" is selected.
3. Click the “Generate” button to begin generating your keys. Move your mouse cursor around randomly in the blank area below the progress bar to generate the key; once finished, you’ll see a progress bar while the key is being generated
4. Save the private key using “Save private key”.
5. Select "Yes" when prompted "Are you sure you want to save this key without a password to protect it?"
6. Comment on your Trello Implementation card or email the text in the top box to [e-mail]

Linux Key Generation

1. Login as the user that will be sending the files (Note: throughout the rest of this guide, we’ll assume the user is named pharos)
2. Run the following command: ssh-keygen -t ed25519
3. When prompted, hit enter to save the file as /home/pharos/.ssh/id_ed25519 (Note: this will overwrite any existing files!)
4. When prompted, hit enter to leave the password blank
5. When prompted, hit enter again to confirm the blank password
6. Comment on your Trello Implementation card or email the contents of /home/pharos/.ssh/id_ed25519.pub to [e-mail]
