How to create a public/private ssh keypair?

Windows

1. Download the complete PuTTY package (free of charge) and install the package
2. Start the PuTTYgen Key Generator
   
3. Choose 'RSA' in the Parameters section at the bottom and keep the number to 2048
4. Click 'Generate' and move the mouse cursor over the PuTTYgen window to generate random data
   
5. Once the keypair is generated, set properties:
   • Key comment - Fill in this field to make your keypair easier to identify later on. Choose for instance 'your_name@computername'.
   • Key passphrase - Choose a passphrase to protect your private key against unauthorized use.
6. Save both public and private ssh keys on your personal computer. We recommend using the names
   • 'id_rsa.pub' for the public key
   • 'id_rsa.ppk' for the private key

Linux / MAC OS X

1. Open a Terminal
2. Enter the command ssh-keygen -t rsa -b 2048

Two files are generate in the .ssh dir:

• private key: id_rsa
• public key: id_rsa.pub
