Paste the text below, substituting in your GitHub email address. ssh-keygen -t rsa -b 4096 -C "your_email@example.com" When you're prompted to "Enter a file in which to save the key," press Enter. This accepts the default file location. At the prompt, type a secure passphrase. If you don't have an existing SSH key that you wish to use, generate one as follows: Open a terminal on your local computer and enter the following: ssh-keygen -t rsa -C "your_email@example.com" Just press to accept the default location and file name. Enter, and re-enter, a passphrase when prompted. You're done. SSH keys provide a more secure way of logging into a virtual private server with SSH than using a password alone.

Accept the default location, and enter a secure passphrase that you (and only you) will remember. Email us the contents of ~/.ssh/id_rsa.pub. You're looking for a pair of files named something like id_dsa or id_rsa and a matching file with a .pub extension. The .pub file is your public key, and the other file is your private key. If you don't have these files (or you don't even have a .ssh directory), you can create them by running a program called ssh-keygen , which is. To generate a pair of public and private keys execute the following command: ssh-keygen -t rsa -b 2048. You can use “dsa" instead of the “rsa" after the -t to generate a DSA key. The number after the -b specifies the key length in bits. After executing the command it may take some time to generate the keys. How to Generate a Public/Private Key Pair for Use With Solaris Secure Shell. Users must generate a public/private key pair when their site implements host-based authentication or user public-key authentication. For additional options, see the ssh-keygen(1) man page.
