# Mirror and history of OpenOTP

It's a mirror and the historical release in a git repository.
I did the mirror because I used OpenOTP with [paper-token](https://github.com/adulau/paper-token) and [hotp-js](https://github.com/adulau/hotp-js).

OpenOTP author is Mark Fullmer.

Open OTP Information

OpenOTP is an implementation of the HOTP protocol using a ZeitControl
Cardsystems ZC3.9 BasicCard and standalone balance reader, standalone Spyrus
PAR2 (Personal Access Reader), or PCSC-Lite supported Smart Card reader.

Included is a C library implementation of the HOTP protocol and
associated user database management, HOTP PAM library, OpenVPN plug-in module,
micro RADIUS server with HOTP support, and utilties for managing the Smart
Card, Spyrus reader, and host side HOTP user database.  The PCSC-Lite
API provides reader support for Smart Card management under FreeBSD and Linux.

The card management, firmware loaders, C API, and authentication methods
have been developed & tested for FreeBSD and Linux.

The PARII HOTP firmware is provided as a pre-compiled binary with source
for the HOTP implementation.  The Spyrus development toolkit and 
Hi-Tech/Microchip C compiler are required for modification.  Run-time
customization of strings is supported via an EEProm loader without need
for the development toolkit & PIC16 compiler.  A Unix tool is included for
downloading firmware to the reader with a Spyrus downloader cable.

Source and Binary for the BasicCard firmware is supplied.  Modification
requires the Windows BasicCard development software available as
a free download from ZeitControl.  A Unix version of bcload implemented
with the PCSC-Lite interface is included.
