This program provides a command line interface for Peter Scott's pwstore library. Specifically, it is possible to generate, validate, and strengthen passwords hashed in the pwstore format.

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
