A simple implementation of OATH-HOTP and OATH-TOTP.
$ luarocks install otp
This is a simple OATH-HOTP and OATH-TOTP implementation in pure lua
that makes use of luaossl for its hashing needs. It can be used as
a generation and verification library and is compatible with the
RFCs 4226 and 6238. It only supports the SHA-1 hashing algorithm
(as specified in the RFCs).
