NAME
yhsm-import-keys - import YubiKey secrets to YubiHSM

SYNOPSIS
yhsm-import-keys --key-handles ... [options]

DESCRIPTION
Read YubiKey token data from standard input, and store it in files or in the YubiHSM internal database. The default mode is to turn each YubiKey secret into an AEAD (Authenticated Encryption with Associated Data) block that is stored in a file on the host computer (one file per YubiKey). This enables validation of virtually unlimited numbers of YubiKey's OTPs. If --internal-db is used, the YubiKey secret will be stored inside the YubiHSM, and complete validation (including counter management) will be done inside the YubiHSM. The internal database is currently limited to 1024 entrys.

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

--public_id_chars num
    number of chars to pad public id to (default: 12)

--key-handles kh
    key handles to use for decoding OTPs. Examples : "1", "0xabcd"

--output-dir dir, --aead-dir dir, -O dir
    base directory for AEADs (default: /var/cache/yubikey-ksm/aeads)

--internal-db
    add entrys to YubiHSM internal database, rather than creating AEAD files

--random-nonce
    use random nonce generated from YubiHSM

INPUT FORMAT
The format of the input matches the export format of various Yubico tools, notably the PHP based An example file, with a single entry for id 4711 would be :
# ykksm 1
123456,ftftftcccc,534543524554,fcacd309a20ce1809c2db257f0e8d6ea,000000000000,,,
(seqno, public id, private uid, AES key, dunno,,,) The #ykksm 1 is a file marker, and has to be on the very first line of input.
