Setting up ssh public key authentication on macOS using a YubiKey 4

Setting up ssh public key authentication on macOS using a YubiKey 4

I largely followed Florin's blog post, but have a few notes to add regarding issues I encountered:

Basic setup notes

  1. I used a YubiKey 4, while the blog describes using a YubiKey NEO. I'm sure a YubiKey 5 would also work. I'm also running macOS 10.13.6.
  2. I installed GPGTools as recommended. However, as I'll note later, it seems that gpg-agent only automatically starts when gpg is used; for ssh, you'll need to ensure it's running.
  3. Before generating your keys, decide what key size you want to use. If you run the list command inside gpg --edit-card, look for the Key attributes line to see what is currently selected. On my YubiKey 4, it defaulted to 2048 bits for all keys:
Key attributes ...: rsa2048 rsa2048 rsa2048

How to break (and re-enable) the native accessibility "delete" action for table views

If you've haven't seen it before, there is a cool accessibility feature in UITableView that allows the user to toggle between different actions. It's really very elegant and it's a powerful and convenient implementation for VoiceOver users on iOS. One could say that it's the VoiceOver version of the swipe-to-delete feature.

To try it out yourselves, open one of the built in apps like Mail or Notes and turn on VoiceOver. If you are afraid to accidentally delete some of your important notes or email, you can also create a new Master-Detail Application in Xcode and run it on your device. Navigate to one of the cells and use the "Rotor" (rotate with two fingers on the screen) to find the "Actions" item. Now you can swipe up and down do toggle between "Activate Item (default action)" and "Delete". If you now double tap, the cell gets deleted instead of selected.

This is the default behavior and you get this accessibility out of the box with UITableView.

Using the "More" button. Of course the simple way that Apple uses in Mail/iOS is not public. rdar://16600859
- (NSString *)tableView:(UITableView *)tableView titleForSwipeAccessoryButtonForRowAtIndexPath:(NSIndexPath *)indexPath {
return @"More";
}
- (void)tableView:(UITableView *)tableView swipeAccessoryButtonPushedForRowAtIndexPath:(NSIndexPath *)indexPath {
NSLog(@"I wanted to be a pretty public API, but then time ran out and they forgot me...");
// Hide the More/Delete menu.
[self setEditing:NO animated:YES];
}

A simple way to detect at runtime if we're running in UIKit legacy mode or the new "flat" variant. Written for our PDF iOS SDK (http://pspdfkit.com), where the precompiled binary needs to detect at runtime in what variant it's running. Want more stuff like that? Follow me on Twitter: http://twitter.com/steipete
// Taken from http://PSPDFKit.com. This snippet is under public domain.
#define UIKitVersionNumber_iOS_7_0 0xB57
BOOL PSPDFIsUIKitFlatMode(void) {
static BOOL isUIKitFlatMode = NO;
static dispatch_once_t onceToken;
dispatch_once(&onceToken, ^{
// We get the modern UIKit if system is running >= iOS 7 and we were linked with >= SDK 7.
if (kCFCoreFoundationVersionNumber >= kCFCoreFoundationVersionNumber_iOS_7_0) {
isUIKitFlatMode = (NSVersionOfLinkTimeLibrary("UIKit") >> 16) >= UIKitVersionNumber_iOS_7_0;
}
