Creating an SSH Key Pair (for Linux, Mac OSX, Windows)

This article explains how to create SSH key pairs on different operating systems for secure authentication.

SSH Key Pairs

SSH key pairs provide secure authentication without passwords, consisting of:

• Private Key: Kept secure on your local machine
• Public Key: Shared with servers for authentication

Linux and Mac OSX

`ash ssh-keygen -t rsa -b 4096 -C 'your-email@example.com' ``n

Windows

Using OpenSSH (Windows 10+)

`cmd ssh-keygen -t rsa -b 4096 -C 'your-email@example.com' ``n

Using PuTTY

1. Open PuTTYgen
2. Generate key pair
3. Save private key
4. Copy public key

Security Best Practices

• Use strong passphrases
• Keep private keys secure
• Regularly rotate keys
• Use appropriate key lengths
