The OATH Toolkit provides components for building one-time password
authentication systems. It contains shared libraries, command line tools and a
PAM module. Supported technologies include the event-based HOTP algorithm
(RFC4226) and the time-based TOTP algorithm (RFC6238). OATH stands for
Initiative for Open Authentication, an industry-wide collaboration to develop
open authentication algorithms.

For secret key management, the Portable Symmetric Key Container (PSKC) format
described in RFC6030 is supported.

The components included in the package are:

* liboath: A shared and static C library for OATH handling.
* oathtool: A command line tool for generating and validating OTPs.
* pam_oath: A PAM module for pluggable login authentication for OATH.
* libpskc: A shared and static C library for PSKC handling.
* pskctool: A command line tool for manipulating PSKC data.
