dpgclj - Diceware™ password generator in Clojure

This project is clojure version of Diceware Password Generator I have written some time ago (in Rust).

The aim is to create an application that could be used to generate easy to remember passwords using the Diceware™ method.

Usage

dpgclj options:

-l:[language] - generate password using specified language. By default only pl (Polish) and en (English) are supported. Dpgclj tries to read all files matching diceware-XY.txt pattern where XY is code for the language (pl, en, es, etc.) - so it is pretty easy to use this app to generate password in any language providing only proper list of words.

-w:[number] - generate password(s) containing specified number of words.

-s:[char] - separate words using provided separator - default is - (dash).

-p:[number] - number of passwords to be generated at once - default is 1.

Please note: order of options does NOT matter. For the sake of simplicity only -l and -w are required.

Examples:

-w:5 -l:en - generates password from English diceware list, consisting of 5 words. Words will be separated by -.

-w:4 -l:pl -s:. - generates single password from Polish diceware list, consisting of 4 words, words will be separated by .

-l:fi -w:8 -p:6 - generates 6 passwords from Finnish diceware list, each password consisting of 8 words, words separated by -.

-p:10 -l:pt -p:100 -s:/ -w:7 - generates 10 passwords from Portugese diceware list, each password consisting of 7 words, each word separated by /

Building project

Dpgclj has been created using leiningen - lein becomes the first requirement - install it before proceeding with any further steps.

Running lein repl

To test dpgclj, or some of its functions, type lein repl.

Executing project

dpgclj could be run in very simple way: lein run. Parameters could also be added.

Building jar...

1. lein uberar results in building complete jar

2. java -jar target/uberjar/dpgclj-0.1.0-SNAPSHOT-standalone.jar. All options could be passed after the name of the jar file to be executed.

Running tests

Dpgclj contains some unit tests, and by default Travis-Ci is used to run tests against each and every commit (or rather push) to the github repository.

It is also possible to run test locally using lein: lein test. This method has one disadvantage - it takes significant time to startup lein itself, so it often takes ~4-5 seconds (or even more) to get info on failing/passing tests.

It is also possible to run tests within Clojure repl, as follows:

1. Run repl (lein repl from withing the folder into which dpgclj was cloned)
2. Load Clojure testing namespace: (use 'clojure.test)
3. Load namespaces containing tests: (use 'dpgclj.crypt-test) and (use 'dpgclj.options-test)
4. Run tests

• (run-all-tests) - run tests from all namespaces loaded
• (run-tests 'dpgclj.options-test) - run test from single namespace
• (run-tests 'dpgclj.options-test 'dpgclj.crypto-test) - run tests from all (explicitly) specified namespaces

If you're using Emacs/Spacemacs with Cider plugin (don't know about other editors/IDE) it is also possible to conveniently run tests from the editor itself.
