Generate KSM Key

Import of key material to an YK-KSM is typically always done via the OpenPGP encrypted/signed Key Provisioning Format. This setup assumes that each YK-KSM system has a private key.

Below is a walk-through of a typical key generation session for a host called crater. As you can see at the end, it generated a key with a key id of 8B88A11B.

After this step you may want to generate AES keys for your YubiKeys, see Generate Keys, and then import them to your KSM, see Import Keys To KSM.

You need a Passphrase to protect your secret key.

We need to generate a lot of random bytes. It is a good idea to perform
some other action (type on the keyboard, move the mouse, utilize the
disks) during the prime generation; this gives the random number
generator a better chance to gain enough entropy.
