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. BUGS
