WEBVTT 00:00.000 --> 00:11.000 Hi, my name is Ronko, and I'm here to give you a rolling tool of Ag plugin S.E. 00:11.000 --> 00:13.000 So, strapping. 00:13.000 --> 00:20.000 As an anyplace, Ag plugin S.E. is a plugin for Ag, which is a simple modern and secure file encryption tool. 00:20.000 --> 00:29.000 But the plugin does is it protects the secrets that are used by Ag using the secure enclave in your Apple device. 00:30.000 --> 00:36.000 The plugin is actually a single binary, which you start by invoking to create a key pair. 00:36.000 --> 00:42.000 The private key you keep to yourself, and the short public key you can send to others. 00:42.000 --> 00:51.000 Using this short public key, you can now encrypt any file on any device, even when you completely different OS. 00:52.000 --> 01:00.000 To decrypt the files, you need the private key, and the secure enclave with which this private key was created. 01:00.000 --> 01:11.000 Now, this particular key was actually configured to require touch ID to operate, so after touching my touch sensor, the file is now decrypted. 01:12.000 --> 01:25.000 There's a whole ecosystem of applications that use Ag, for example, you can use Ag as a back end of a password manager, and use this plugin to conveniently access your passwords with just a touch. 01:25.000 --> 01:27.000 Now let's have a look at the word. 01:27.000 --> 01:36.000 All the cryptographic operations used by this plugin are provided by Apple Crypto Kit. 01:36.000 --> 01:40.000 Apple Crypto Kit is switched on, so that's why this plugin is also implemented entirely in Swift. 01:40.000 --> 01:44.000 Apple Crypto Kit is also the only dependency that this plugin has. 01:44.000 --> 01:58.000 Now, quickly, it itself is not a cross platform, but Swift Crypto is an open source and open replacement for cryptocurrency that is supported on both Linux and Windows. 01:59.000 --> 02:07.000 Swift Crypto doesn't support the Apple only secure enclave APIs, but it does support all the other preventives that are necessary to encrypt files. 02:07.000 --> 02:13.000 And that's actually all you need on these other operating systems. 02:13.000 --> 02:23.000 The build of the plugin is also a cross platform, all you need is the Swift twitching, so now need for Xcode, which was a problem up until today. 02:23.000 --> 02:27.000 All you have to do is run Swift build on any platform and you have the plugin built. 02:28.000 --> 02:34.000 Unfortunately, if, like me, you use our pandemics, there are some complications. 02:34.000 --> 02:44.000 The Swift twitching uses G-lipsy, so that means you cannot simply call the compiler on a user-based system like our pandemics. 02:44.000 --> 02:57.000 And what goes to describe the couple of ways of getting a Swift apps to run on our pandemics, the latest easiest way is to use a cross compilation to use Swift on macOS to do cross compiling and create a new platform. 02:57.000 --> 03:06.000 Compiling and create a static Linux binary that works on any Linux version, even our pandemics. 03:06.000 --> 03:16.000 Combined with a custom script that I wrote on the GitHub, with these builders of this plugin, create an installed our pandemics package. 03:16.000 --> 03:26.000 The downside of this approach is that the binary is the static Linux binary that are generated are still much bigger than what they actually could be. 03:26.000 --> 03:35.000 I hope that this is improved in the future, or even better that Swift is supported on user-based Linux versions. 03:35.000 --> 03:45.000 The plugin itself is pretty well tested, and there are integration tests, but most of the majority of the code is covered using unit tests. 03:45.000 --> 03:50.000 Of course, you can simply run the tests on any platform that is in Swift test. 03:50.000 --> 03:59.000 Swift test also has flags to collect coverage information, but without X codes, how you display this coverage information is up to you. 03:59.000 --> 04:11.000 I wrote a script in Swift that creates a summary of all this coverage data of your tests, and also generates browser profiles that you can inspect your code from within your web browser. 04:11.000 --> 04:19.000 The script also generates a batch at put on your readme, your readme file. 04:19.000 --> 04:35.000 So, I use them as my code editor, obviously, and to be able to see the coverage information in my editor, I have a support for Swift to deliver in coverage applied in. 04:35.000 --> 04:46.000 Together with the test, this allows you to do some efficient tests within development. 04:47.000 --> 04:52.000 So, that's it. That was my quick experience of implementing a Swift code platform. 04:52.000 --> 05:01.000 Swift crypto app. You can read some letters at the bottom of the post, and be sure to check out all the other open source projects that I mentioned. Thank you.
