2. Enter the number of bits for the key. Ensure that the RSA key size is between 1024 and 4096.
NOTE:
• CMC may not display a message if you add keys less than 1024 or greater than 4096, but when you try to log in
with these keys, it fails.
• CMC accepts RSA keys up to key strength 4096, but the recommended key strength is 1024.
3. Click Generate, and move the mouse in the window as directed.
After the key is created, you can modify the key comment field.
You can also enter a passphrase to make the key secure. Ensure that you save the private key.
4. You have two options for using the public key:
• Save the public key to a file to upload later.
• Copy and paste the text from the Public key for pasting window when adding the account using the text option.
Generating public keys for systems running Linux
The ssh-keygen application for Linux clients is a command line tool with no graphical user interface. Open a terminal window and at the
shell prompt type:
ssh-keygen –t rsa –b 1024 –C testing
where,
–t must be rsa.
–b specifies the bit encryption size between 768 and 4096.
–c allows modifying the public key comment and is optional.
The < passphrase > is optional. After the command completes, use the public file to pass to the RACADM for uploading the file.
