== Generate KSM Key == Import of key material to an YK-KSM is typically always done via the OpenPGP encrypted/signed KeyProvisioningFormat 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 [[GenerateKeys]], and then import them to your KSM, see [[ImportKeysToKSM]]. user@crater:~$ gpg --gen-key gpg (GnuPG) 1.4.9; Copyright (C) 2008 Free Software Foundation, Inc.

(0) Key does not expire at all Is this correct?

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. .+++++++++++++++++++++++++..+++++.+++++++++++++++++++++++++...+++++++++++++++.++++++++++.++++++++++++++++++++++++++++++++++++++++.++++++++++>++++++++++......++++++++++..++++++++++++++++++++..++++++++++++++++++++++++++++++++++++++++....+++++.+++++...+++++.++++++++++.+++++++++++++++.+++++..+++++.++++++++++.+++++++++++++++..+++++>++++++++++>+++++.................................>+++++..............+++++^^^ gpg: /home/user/.gnupg/trustdb.gpg: trustdb created gpg: key 8B88A11B marked as ultimately trusted public and secret key created and signed. gpg: checking the trustdb gpg: 3 marginal(s) needed, 1 complete(s) needed, PGP trust model gpg: depth: 0 valid: 1 signed: 0 trust: 0-, 0q, 0n, 0m, 0f, 1u pub 1024D/8B88A11B 2009-12-14 Key fingerprint = 9B18 20A2 F02E 3C3B 84E3 44F5 AE72 7967 8B88 A11B uid YK-KSM crater Import Key sub 2048g/140A17F1 2009-12-14 user@crater:~$
