# yhsm-daemon(1)

Allow multiple users of a YubiHSM.

## NAME

yhsm-daemon ‐ Allow multiple users of a YubiHSM.

## SYNOPSIS

**yhsm-daemon \[*options*\] \[device\] \[port\]**

## DESCRIPTION

This is a daemon to allow multiple users of a YubiHSM without requiring permission to use the device. The daemon listens on a TCP port on localhost and allows multiple connections to share a YubiHSM. Access the YubiHSM via the daemon by specifying a device string following the yhsm://\<host\>:\<port\> syntax:

hsm = YHSM('yhsm://localhost:5348')

Note that the daemon and clients need to share the same version number to be compatible.
