grunt-hash-file-contents

Takes a list of files and converts them into a hash. Useful for comparing versions of a codebase as small changes in code result in a greatly different hash.

Install

$ npm install grunt-hash-file-contents --save-dev

Usage

grunt.loadNpmTasks('grunt-hash-file-contents');

grunt.initConfig({
  hashFileContents: {
    algorithm: 'md5',
    encoding: 'hex',
    files: [
      'src/**/*.*'
    ],
    target: 'target/codebaseHash.txt'
  }
});

grunt.registerTask('default', ['hashFileContents']);

Options

algorithm

Type: string Default: md5

The name of the hashing algorithm to use. This can be one of hte hashing algorithms available to node, the available algorithms depend on the version of OpenSSL on the platform. Examples are sha256, sha512, md5 etc. It is recommended to stick to quick algorithms as a secure has isn't really the point here.

encoding

Type: string Default: hex

The encoding of the resultant hash. Can be one of 'hex', 'binary' or 'base64'.

files

Type: array[string] Required

The array of blobbing patterns to use to fetch the files to turn into a hash. This is required.

target

Type: string Required

The name of the target file, this will contain the hash.
