The OATH (Open AuTHentication) Toolkit provides various components for building one-time password (OTP) authentication systems:
oathtool, a command-line tool for generating & validating OTPs.
liboath, a C library for OATH handling.
pskctool, a command-line tool for manipulating secret key files in the Portable Symmetric Key Container (PSKC) format described in RFC6030.
libpskc, a shared and static C library for PSKC handling.
pam_oath, a PAM module for pluggable login authentication.
