     "The @dfn{OATH} (Open AuTHentication) Toolkit provides various components
for building one-time password (@dfn{OTP}) authentication systems:

@itemize
@item @command{oathtool}, a command-line tool for generating & validating OTPs.
@item @code{liboath}, a C library for OATH handling.
@item @command{pskctool}, a command-line tool for manipulating secret key
files in the Portable Symmetric Key Container (@dfn{PSKC}) format
described in RFC6030.
@item @code{libpskc}, a shared and static C library for PSKC handling.
@item @code{pam_oath}, a PAM module for pluggable login authentication.

Supported technologies include the event-based @acronym{HOTP, Hash-based Message
Authentication Code One-Time Password} algorithm (RFC4226), the time-based
@acronym{TOTP, Time-based One-Time Password} algorithm (RFC6238), and
@acronym{PSKC, Portable Symmetric Key Container} (RFC6030) to manage secret key
