Create a key pair To create a key pair, at a command prompt, type the following command: sn –k In this command, file name is the name of the output file containing the key pair.
How to Create a Public/Private Key Pair
Generate Rsa Public Private Key
The standard procedure for creating a Secure Shell public/private key pair follows. For information on additional options, see ssh-keygen(1).
- Creates a 2048-bit RSA key pair with the specified name. Amazon EC2 stores the public key and displays the private key for you to save to a file. The private key is returned as an unencrypted PEM encoded PKCS#1 private key.
- My problem is that the keys generated by this code are always the same. How would I generate a unique set of keys every time? My test code is below.: note: the 'privatekey' parameter here is the original private key. In order for the keys to be changed I need to verify that the private key is valid. In Default.aspx.cs.
How To Generate Rsa Key
Start the key generation program.
Enter the path to the file that will hold the key.
By default, the file name id_rsa, which represents an RSA v2 key, appears in parentheses. You can select this file by pressing Return. Or, you can type an alternative filename.
The public key name is created automatically and the string .pub is appended to the private key name.
Enter a passphrase for using your key.
This passphrase is used for encrypting your private key. A good passphrase is 10–30 characters long, mixes alphabetic and numeric characters, and avoids simple English prose and English names. A null entry means no passphrase is used, but this entry is strongly discouragedfor user accounts. Note that the passphrase is not displayed when you type it in.
Re-enter the passphrase to confirm it.
Check the results.
The key fingerprint (a colon-separated series of 2 digit hexadecimal values) is displayed. Check that the path to the key is correct. In the example, the path is /home/johndoe/.ssh/id_rsa.pub. At this point, you have created a public/private key pair.
Copy the public key and append the key to the $HOME/.ssh/authorized_keys file in your home directory on the remote host.
