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. I used a YubiKey 4, while the blog describes using a YubiKey NEO.

• When generating a SSH key with PuttyGen, the key is stored with the.ppk extension; Run 'full path to your pageant.exe' 'full path to your key.ppk' (must be quoted). This will execute the pageant service and register your key (after entering the password). Set environment variable GITSSH=full path to plink.exe (must not be quoted).
• GitHub Enterprise Server Authentication Connecting to GitHub with SSH Generating a new SSH key and adding it to the ssh-agent Generating a new SSH key and adding it to the ssh-agent After you've checked for existing SSH keys, you can generate a new SSH key to use for authentication, then add it to the ssh-agent.

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:

These correspond to the signature key, encryption key, and authentication key. (I believe only the authentication key is used for ssh.)

Running the key-attr admin subcommand lets you change these:

(Note that the OpenPGP applet only works with RSA, not ECC, so don't choose that.)

4. After generating keys, ssh-add -L may not initially show anything:

This is because gpg-agent changed how it works a few years ago, removing some options such as write-env-file (per this comment, which Florin's instructions use.

To get gpg-agent and ssh-agent to work together, you can use a simplified /.gnupg/gpg-agent.conf:

Osx Generate Ssh Key Github

and then kill any running gpg-agent process so that it picks up the new configuration.

Since the .gpg-agent-info file is no longer created by gpg-agent, you must also change your .bash_profile to use the GPG agent ssh socket directly. I also added a line here to ensure that the gpg-agent is running:

Mac Generate Ssh Key For Github

(This is taken from @drduh's YubiKey guide.)

After updating this, launch a new shell, and ssh-add -L should now show you your public key, and you can follow the rest of the directions provided.

Requiring touch

I wanted to require a touch any time I tried to use my YubiKey for ssh authentication to prevent rogue processes from using the key while it's plugged in.

You can use the YubiKey Manager CLI to require this; I installed it via Homebrew.

After installed, use the ykman openpgp touch subcommand to configure the touch settings:

(Again, you control the three keys separately.)

Problems with certain versions of the YubiKey 4

I attempted to add my SSH public key to my GitHub account and came across this perplexing error:

Mac Get Ssh Key

Key is weak. GitHub recommends using ssh-keygen to generate a RSA key of at least 2048 bits.

I'd initially used a 2048-bit RSA key, so using the key-attr subcommand I described above, I tried generating a 4096-bit key, but GitHub gave the same error message.

After some searching, I came across this issue. Basically, due to a security issue in certain versions of the YubiKey 4 (4.2.6-4.3.4), GitHub rejects keys generated on these YubiKeys as weak. There are basically two workarounds:

1. Generate a keypair off of the card and then load it onto the YubiKey.
2. Replace the YubiKey with a newer one. Thankfully, Yubico will replace your affected YubiKey 4 for free.
