pwstore-cli
===========

About
-----

This is a simple command line interface to Peter Scott's pwstore
library.  It allows

 * generation of password hashes from a given password;
 * verification that a given password hash match a given password; and
 * strengthening a given password hash.

Building and Installing
-----------------------

In most cases you can build and install this program using the regular
cabal commands

    $ cabal configure
    $ cabal build
    $ cabal install

Alternatively, if you wish to build the program such that it uses
`pwstore-purehaskell`, rather than `pwstore-fast` then disable the
"fast" flag.  That is, change the configure command to

    $ cabal configure -f '-fast'

Examples
--------

This is an example shell session running a few variants of the pwstore
command.

    $ pwstore
    Password:
    Repeat password:
