* pkcs11-hmacmd5
*
* Prints the MD5 HMAC of the standard input, using the PKCS#11 device.
*
* Usage:
* pkcs11-hmacmd5 [-m module] [-s $slot] [-n] [-p $pin]
* -m: PKCS#11 provider module. This must be the full
* path to a shared library object implementing the
* PKCS#11 API for a device.
* -s: Slot
* -p: PIN
* -n: don't log in to the PKCS#11 device
* -k: key name for the HMAC
