NB: This document describles a 'Old-School' way of using Yubikey with SSH

Modern OpenSSH has native support for FIDO Authentication. Its much simpler and should also be more stable with less moving parts. OpenSSH also now has support for signing arbitary files witch can be used as replacement of gnupg. Git also supports signing commits/tags with ssh keys.

Pros of FIDO

• Simpler stack / less moving parts
• Works directly with ssh, ssh-add and ssh-keygen on most computers
• Simpler
• Private key can never leave the FIDO device

Cons of FIDO

Revert / Undo a Gist Commit

It was not exactly obvious. Here's how to revert a Gist commit!

Checkout the gist like a normal git repo:

# replace the Gist ID with your own
git clone git@github.com:cc13e0fcf2c348cc126f918e4a3917eb.git

Treat it like a normal repo. Edit, force push, etc.

Just run the script in your terminal like this...

node script-file.js > log-file.txt

This tells the shell to write the standard output of the command node script-file.js to your log file instead of the default, which is printing it to the console.

This is called redirection and its very powerful. Say you wanted to write all errors to a separate file...

node script-file.js >log-file.txt 2>error-file.txt
Now all console.log are written to log-file.txt and all console.error are written to error.txt
