Foxify

foxify is a gem which provides resumable digest implementations in ruby by leveraging the power of Go

The classes Foxify::ResumableSHA256 and Foxify::ResumableSHA1 can be safely serialized and restored at any point in time and digest calculation can be resumed. This is an advantage in stateless application servers where i.e. large files are uploaded in chunks and you want to resume digest calculation in each request.

Requirements

• Ruby 3.3+
• Go 1.23+

Installation

Add the foxify gem to your Gemfile:

gem "foxify"

Update your bundle:

bundle install

NOTE: You need a go-lang compiler version 1.23+ in your environment to compile the native part of this gem.

Usage

Foxify::ResumableSHA256

Simple usage without serializing:

require 'foxify'

digest = Foxify::ResumableSHA256.new
digest.update("The quick brown fox jumps over the lazy dog")
digest.hexdigest # returns "d7a8fbb307d7809469ca9abcb0082e4f8d5651e46d3cdb762d02d0bf37c9e592"

Usage with serializing and resuming later on:

require 'foxify'

digest = Foxify::ResumableSHA256.new
digest.update("The quick brown fox ")
data = digest.to_msgpack

# store data somewhere and later reload it
restored = Foxify::ResumableSHA256.from_msgpack(data)
restored.update("jumps over the lazy dog")
restored.hexdigest # returns "d7a8fbb307d7809469ca9abcb0082e4f8d5651e46d3cdb762d02d0bf37c9e592"

Foxify::ResumableSHA1

Simple usage without serializing:

require 'foxify'

digest = Foxify::ResumableSHA1.new
digest.update("The quick brown fox jumps over the lazy dog")
digest.hexdigest # returns "2fd4e1c67a2d28fced849ee1bb76e7391b93eb12"

Usage with serializing and resuming later on:

require 'foxify'

digest = Foxify::ResumableSHA1.new
digest.update("The quick brown fox ")
data = digest.to_msgpack

# store data somewhere and later reload it
restored = Foxify::ResumableSHA1.from_msgpack(data)
restored.update("jumps over the lazy dog")
restored.hexdigest # returns "2fd4e1c67a2d28fced849ee1bb76e7391b93eb12"
