Command line interface for Peter Scott's pwstore library

root

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
