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.
