NAME

       yhsm-generate-keys - Generate AEADs with secrets for YubiKeys using a YubiHSM

SYNOPSIS

       yhsm-generate-keys --key-handles KEY_HANDLES --start-public-id START_ID [options]

DESCRIPTION

       With  this  tool,  a YubiHSM can generate random secrets (using it's internal true random number generator), and these secrets protected in
       AEAD files can be stored on the host computer.

       The AEADs will be ready to be used by for example yhsm-yubikey-ksm(1) ), as a part of a YubiKey OTP validation service.

       To program YubiKeys with the generated secrets, it is possible to decrypt the AEADs (knowledge of the AES key used inside  the  YubiHSM	is
       required) using yhsm-decrypt-aead(1)

OPTIONS

       -D, --device
	      Device file name (default: /dev/ttyACM0).

       -v, --verbose
	      Enable verbose operation.

       --debug
	      Enable debug printout, including all data sent to/from YubiHSM.

       -O dir Base output directory (default: /var/cache/yubikey-ksm/aeads).

       -c integer
	      Number of AEADs to generate.

       --public-id-chars integer
	      Number of chars in generated public ids (default: 12). Changing this might not work well.

       --key-handles kh [kh ...]
	      Key handles to encrypt the generated secrets with. Examples : "1", "0xabcd".

       --start-public-id id
	      Public id of the first generated secret, in modhex.

EXIT STATUS

       0   Secrets generated successfully.

       1   Failed to generate secrets.

NAME

       ykpamcfg - Manage user settings for the Yubico PAM module.

SYNOPSIS

       ykpamcfg [-1 | -2] [-A] [-v] [-h]

OPTIONS

       -1     use slot 1.  This is the default.

       -2     use slot 2.

       -A action
	      choose action to perform. See ACTIONS below.

       -v     enable verbose mode.

ACTIONS

       add_hmac_chalresp
	      The PAM module can utilize the HMAC-SHA1 Challenge-Response mode found in YubiKeys starting with version 2.2 for offline authentica-
	      tion.  This action creates the initial state information with the C/R to be issued at the next logon.

	      The utility currently outputs the state information to a file in the current user's home directory (~/.yubico/challenge-123456 for a
	      YubiKey with serial number API readout enabled, and ~/.yubico/challenge for one without).

	      The  PAM module supports a system wide directory for these state files (in case the user's home directories are encrypted), but in a
	      system wide directory, the 'challenge' part should be replaced with the username. Example : /var/yubico/challenges/alice-123456.

	      To use the system-wide mode, you currently have to move the generated state files manually and configure the PAM module accordingly.

EXAMPLE

       First, program a YubiKey for challenge response on Slot 2 :

	      $ ykpersonalize -2 -ochal-resp -ochal-hmac -ohmac-lt64 -oserial-api-visible
	       ...
	      Commit? (y/n) [n]: y
	      $

       Now, set the current user to require this YubiKey for logon :

	      $ ykpamcfg -2 -v
	       ...
	      Stored initial challenge and expected response in '/home/alice/.yubico/challenge-123456'.
	      $

       Then, configure authentication with PAM for example like this (make a backup first) :

       /etc/pam.d/common-auth (from Ubuntu 10.10) :

	      auth required  pam_unix.so nullok_secure try_first_pass
	      auth [success=1 new_authtok_reqd=ok ignore=ignore default=die]   pam_yubico.so mode=challenge-response
	      auth requisite pam_deny.so
	      auth required  pam_permit.so
	      auth optional  pam_ecryptfs.so unwrap
