Many-file-hashes NPM

many-file-hashes

Get the hashes of multiple files.

Uses path to resolve file path.

use

Simplest use is like this (outputs sha1 hashes in hex encoding):

var manyHashes = require('many-file-hashes')

manyHashes([ './file1.ext', './file2.ext' ], function(err, hashes) {
	/*
	hashes = [
		{
			original: './file1.ext',
			fullPath: '/tmp/folder/file1.ext',
			hash: 'cd92815bf6273acbaf834b9faed277c722068291'
		}, {
			original: './file2.ext',
			fullPath: '/tmp/folder/file2.ext',
			hash: 'f6273acbaf834b9faed277c722068291cd92815b'
		}
	]
	*/
})

first param

You can pass in any of these as the first parameter:

string : which is interpreted is a single file
array : which is interpreted as a list of files
object : which is an options object, see below

not supported

Does not do recursive directory walking.

Must be actual files.

Use something like glob to walk directories.

all options

The first parameter can be an object, with the following optional parameters, like this:

var manyHashes = require('many-file-hashes')

var options = {
	files: [ './file.ext' ], // an array of *files* (directories not supported)
	encoding: 'base64', // any node.js encoding type: http://nodejs.org/docs/v0.4.9/api/crypto.html#hash.digest
	hash: 'sha512', // any node.js hash type: http://nodejs.org/docs/v0.4.9/api/crypto.html#crypto.createHash
	cwd: '.' // current working directory, used to resolve file
}

manyHashes(options, function(err, hashes) {
	/*
	hashes = [
		{
			original: './file.ext',
			fullPath: '/tmp/folder/file.ext',
			hash: 'ZOSB36hJrh/oflExNSTXa0YmdkJ9KXrOEtrukC5hwLx1FR0ySjPMbFB1RkcYB4aKlATOA+AgNl4Y/cvRZitsDg=='
		}
	]
