harpo 1.0.3

A set of functions for numeric encryption and decryption. This is also a practical implementation of my algorithms for encryption and decrpytion.

Harpo

About

Harpo is a small library to numerically decrypt/encrypt letters, words, and phrases! Harpo is written in Dart and I thought I'd practice some Dart.

Installation

"Naked Installation"

Simply download the file and place it in your project together with all the other files ending in .dart.

Adding to your project

To add Harpo to your project's dependencies, add this to your project's pubspec.yml:

From GitHub

dependencies:
  ...
  harpo:
    git: git://github.com/iammdsa/harpo.git

From Pub.dev

dependencies:
  ...
  harpo: ^1.0.3

The three dots represent anything else that you might have in the dependencies section. Having done that, re-fetch your project's dependencies by running this in the project's root directory:

$ dart pub get
