klefki

The dependency checker

Simple substitution cipher module. It basically consists of substituting every plaintext character for a different ciphertext character. It differs from the Caesar cipher in that the cipher alphabet is not simply the alphabet shifted, it is completely jumbled.

Installation

npm install klefki --save

Usage

var klefki = require('klefki'),
      _word = 'abracadabra',
      _myKey = 'myKey',
      _cipher = '';
      _cipher = klefki.ciphers.simpleSubstitution.encrypt(_word, _myKey);
      klefki.ciphers.simpleSubstitution.decrypt(_cipher) === _word; // true

Tests

npm test
