lua-scrypt
==========

lua-scrypt is a binding to libscrypt which is a password crypting and
verification library.  lua-scrypt uses the [libscrypt][] library and
provides a simple interface for hashing and verifying passwords.

    local scrypt = require "scrypt"

    local hash = scrypt.hash_password("Hello world")

    assert(scrypt.verify_password(hash, "Hello world"))

Installation
============

To compile lua-scrypt, on platforms with libscrypt 1.21 or later run,

    $ make CFLAGS+=-DTRUST_LIBSCRYPT_SALT_GEN

for platforms with older versions (earlier than 1.21) of libscrypt run,

    $ make

To install lua-scrypt, run,

    $ make install

Originally, [Rob Kendrick][] wrote `lua-scrypt` back when there wasn't a shared
library for the scrypt algorithm.  The returned values were binary and a bit
messy, and as such they are not supported by this version of the library.
