![]() I've tried going through several tutorials but none of them solve this problem. exe will run and I get my icon, though it's I get an error in doing so the installer won't work at all. Outside the function, I get an error message. In my main.js file, I have code to attach the icon but I can only make it work inside of the createWindow function. exe and installer but the icons aren't mine. It’ll make you a better programmer.I've got my electron build files for a win. I recommend watching this 2 minute keytar solo (starting around 2:30) from Kool & the Gang. That’s it! Node-keytar offers a simple way to better secure your application. Additionally, I think it’s cleaner and clearer to the user if the access control list has your app name and it’s icon, instead of MyApp Helper and the generic app icon which is what you get when a renderer sets it. If you set a password from the main process and then attempt to get it from a renderer process, it’ll prompt a permissions dialog for the user (this is macOS only, Windows doesn’t seem to mind either way). One other important note: I recommend you only call node-keytar from the main process. You can follow this guide on how to do that. When installing node-keytar for use in an Electron app, it needs to be compiled against Electron’s version of v8. Now you can leverage node-keytar your Electron application using the same methods outlined above. So no other application can access your saved password(s) unless the user explicitly grants permission. If you try to getPassword on a password that was created by another app, it’ll prompt a dialog verifying that’s okay. That may or may not have design implications in your app if you are getting it a lot. Yay! This method takes around 40ms to complete on my mid-2015 MacBook Pro, probably because of the time it takes to decrypt. const secret = keytar.getPassword( 'KeytarTest', 'AccountName') Let’s retrieve the password we just stored. Remember that the user could change these values at any time, so make sure your code handles scenarios where the user deletes your password data from their store unexpectedly. This is nice because it’s not a good experience when an app is constantly prompting the user to access the Keychain. Generating an icon Generating your icon can be done using various conversion tools found online. (When you package your Electron app, this value will be your app’s name and only your app will have access without prompting). The purpose of this guide is to walk through the process of generating and setting an app icon, as well as setting installer and setup icons. Because node.js added the password, any node.js process later on can access it without prompting the user. In Keychain, if you right click the KeytarTest row > Get Info, then click Access Control, you’ll see: However, running replacePassword on a non-existent service and account will create a new one, so it’s like an upsert. ![]() If we run addPassword again on a service and account that’s already in the store, the method will return false and it won’t be updated. Run that and you should see something like below in mac OS’s Keychain app. For example, if you were storing an access token to a 3rd party API like StackExchange, I’d call it just that. account, as expected, is the account name. ![]() In an actual Electron app, the service parameter will be your app name. Keytar.addPassword( 'KeytarTest', 'AccountName', 'secret') * addPassword(service, account, password) ![]() The icon should be called icons.icns or icon.png at it should be at least 515x512 in macOS. Just npm install keytar create an index.js file and add the following: /** Create a /build folder before building your Electron app and place your custom icon there: The icon should be called icon.png or icon.ico and it should be at least 256x256 in Windows. Note, we’re using the word “password” here loosely - “password” is just a string and it could instead be an API access token. It gives you methods like getPassword, addPassword, and replacePassword that get, add, modify, and delete entries from the OS’s password store. APIs for these are available in C++ for each of them, so we need a native node addon that provides bindings for those APIs to Javascript. Mac OS has Keychain, Windows has Credentials Manager, and Linux has Gnome Keyring. Mac, Windows, and Linux all offer secure solutions to do this by using an encryption key derived from the user’s login. ![]() TL DR Code for this example is here under the storing-sensitive-data folder.Ĭcnokes/electron-tutorials- Collection of small sample Electron apps. How do you do that securely? Simply storing it in plain text in an unprotected file can be a security issue. Many Electron apps interact with a remote web service or API, which probably means the application has to store credentials (could be API access tokens, password, etc) for that. ![]()
