encryptor's Introduction

ENCryptor

Overview

ENCryptor is an engine powering our awesome Encrypto app, now open source.

Installation

Preferred way of installation is through CocoaPods

pod 'ENCryptor', :git => 'https://github.com/MacPaw/ENCryptor.git'

Otherwise, you can build the project and copy ENCryptor.framework to your project.

Usage

Opening (viewing hint and preview, checking password)

self.archiveOpener = [ENArchiveOpener openerWithArchiveURL:...];
self.archiveOpener.delegate = self;

NSString *hint = self.archiveOpener.hint;
...
if ([self.archiveOpener checkPassword:password]) {
	NSImage *preview = self.archiveOpener.preview;
}

Encrypting

self.encryptor = [ENEncryptor encryptorWithSourceURLs:@[...]];
self.encryptor.delegate = self;

[self.encryptor encryptWithPassword:password hint:hint preview:preview];
...
- (void)encryptor:(ENEncryptor *)encryptor didFinishWithResultURL:(NSURL *)resultURL {
// resultURL now contains resulting .crypto file located somewhere in temporary directory
}

Decrypting

self.decryptor = [ENDecryptor decryptorWithArchiveURL:resolvedInputURL];
self.decryptor.delegate = self;

[self.decryptor decryptWithPassword:password];
...
- (void)decryptor:(ENDecryptor *)decryptor didFinishWithResultURL:(NSURL *)resultURL {
// resultURL now contains unarchived file or directory somewhere in temporary directory
}

Demo

ENCryptor comes bundled with encrypto-cli as demo, also available for installation through homebrew tap

brew tap macpaw/taps
brew update
brew install encrypto-cli
$ encrypto-cli
usage: encrypto-cli encrypt <input> --output <output folder>
                    decrypt <input> --output <output folder>
                    preview <input>

encryptor's Issues

GUI source

Hey there! Is there no way to get gui part source code?

Instalation on Linux-based OS

I've recently lost my Macbook due to motherboard failure.

I managed to recovery my encrypted files, but don't have any macOS device available to use Encrypto in order to retrieve the data on those files.

My question is: Is it possible to install ENCryptor (or Encrypto app) on a Linux machine?

Carthage support

Hi! Great work

What about carthage's integration for it? Cocoapods isn't so good now!

Use GCM instead of CBC mode for AES encryption

The CBC block mode is no longer the safest mode available [1, 2].

Instead GCM should be used especially since it has authentication and integrity as a security properties, desirable when sending a self-contained encrypted file to symmetric decryption over a potentially insecure channel.

CryptoCommon has GCM routines and you can see an example here: https://opensource.apple.com/source/CommonCrypto/CommonCrypto-60027/CCRegression/CommonCrypto/CommonCryptoSymGCM.c.auto.html
