    simhash

    A node module to calculate the simhash (http://matpalm.com/resemblance/simhash/)

    Installation

    npm install simhash

    Example

    Simhash is hash that returns similar hash(es) for similar input - in contrast to other hashing algorithms.

    // will use crc32 as crypto algorithm as standard
    var simhash = require('simhash')();
     
    var result1 = simhash(['a', 'list', 'of', 'a', 'couple', 'of', 'tokens']);
    // return1 is [0,0,0,1,0,0,1,1,1,0,1,1,0,1,1,0,1,0,0,0,1,1,0,1,0,1,0,1,0,0,1,0]
     
    var result2 = simhash(['a', 'list', 'of', 'a', 'couple', 'of', 'tokens', '!']);
    // result2 is [0,0,0,1,0,0,0,1,1,0,0,1,0,1,1,0,1,0,0,0,1,1,0,1,0,1,0,1,0,0,1,0]

    You can also choose to use another algoritm than the standard crc32 one

    var simhash = require('simhash')('md5');
     
    var result = simhash(['a', 'list', 'of', 'a', 'couple', 'of', 'tokens']);
