Do not store this on a shared file system or a folder on your computer that is shared. The file location of the private key MUST be a place that only you have access to. You will be prompted to select a location to save the private key. Click Yes or go back and add a key passphrase. If you've chosen not to save a key passphrase you will be asked again if you're sure. To convert the key to OpenSSH format, select "Export OpenSSH key" from the Conversions menu. Most people enter their email address here or you can enter something that reminds you this was generated for CCR use.

Changing the default "Key comment" may also be desirable to the user.

If you choose to set one, enter it in the "Key passphrase" box. However, every time you use the key, you will need to enter the passphrase. This is helpful if your machine is compromised and your key is stolen, the hacker would need the passphrase associated with the key to utilize it.

For the utmost in security, you can enter a passphrase for your private key.

Before doing so you might want to consider: Once this is complete, you must now convert the key pair generated by MobaKeyGen into the OpenSSH format that CCR uses on its Linux servers. As you move your mouse around, you'll see the bar move across the window indicating it's working on generating your random, unique key. Anything less than this is insecure Then click the Generate button and move your mouse around the empty area at the top of the GUI. We HIGHLY recommend you change the "Number of bits in a generated key:" from the default of 2048 to 4096 (last option at the bottom of the GUI). Under 'type of key to generate' select RSA.

To generate a public/private key pair, start the MobaXterm SSH Key Generator (MobaKeyGen) found under the MobaXterm Tools menu.

Keeping your private key secure is of the utmost importance if you choose to use SSH keys rather than a password to connect to CCR servers. Please read the information above if you don't know what this means. If you do not already have a SSH key pair, you will need to generate one. NOTE: We recommend version 21+ as we've received reports that earlier versions have issues with key generation.

Most are very similar to MobaXterm however, you will need to look up documentation online for configuring these.ĭownload and install MobaXterm (the free version is appropriate for home/academic use) You can use other SSH clients such as Putty.

In this example, we’re going to demonstrate how to create a new key pair using MobaXterm, load a private key into MobaXterm and then connect to CCR's servers. More details For all practical purposes both are equally secure until, or unless, either is compromised.

Ed25519 encryption is believed to be about as secure as a 3K RSA key. There are several encryption algorithms supported by ssh - generally RSA or Ed25519 are the only ones you should use now. In this event the impact of a stolen private key could be minimized. You can create multiple key pairs, and use different key pairs for (for example) different servers. This does not mean you have to enter the password every time you use the key pair you can add the key to an ssh authentication agent, entering the password once, then use the key pair without the password.

Clearly, passworded keys are more secure than non‑passworded keys. SSH key pairs can be generated with or without password for the key. SSH uses key pairs - a safely shareable public key and a private key.
