## NAME

nvme-gen-dhchap-key - Generate a host DH-HMAC-CHAP key

## SYNOPSIS

    nvme gen-dhchap-key [--hmac=<hmac-id> | -h <hmac-id>]
                          [--secret=<secret> | -s <secret> ]
                          [--key-length=<len> | -l <len> ]
                          [--nqn=<host-nqn> | -n <host-nqn> ]

## DESCRIPTION

Generate a base64-encoded DH-HMAC-CHAP host key in the form: DHHC-1:00:ia6zGodOr4SEG0Zzaw398rpY0wqipUWj4jWjUh4HWUz6aQ2n: and prints it to stdout.

## OPTIONS

-h <hmac-id>
--hmac=<hmac-id>

-s <secret>
--secret=<secret>

  Secret value (in hexadecimal) to be used for the key. If none are provided a random value is used.

-l <len>
--key-length=<len>

  Length of the resulting key. Possible values are 32, 48, or 64.

-n <hostnqn>
--nqn=<hostnqn>

  Host-NQN to be used for the transformation. This parameter is only valid if a non-zero HMAC function has been specified.
