.SH NAME
yhsm-generate-keys \(hy Generate AEADs with secrets for YubiKeys using a YubiHSM

.SH SYNOPSIS
.B yhsm\-generate\-keys \-\-key\-handles KEY_HANDLES \-\-start\-public\-id START_ID
[\fIoptions\fR]

.SH 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
.BR 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
.BR yhsm-decrypt-aead (1)
.

.SH OPTIONS

.TP
\fB\-c integer\fR
Number of AEADs to generate.
.TP
\fB\-\-public\-id\-chars integer\fR
Number of chars in generated public ids (default: 12). Changing this might not work well.
.TP
