Native Secure Enclave backed ssh keys on MacOS

It turns out that MacOS Tahoe can generate and use secure-enclave backed SSH keys! This replaces projects like https://github.com/maxgoedjen/secretive

There is a shared library /usr/lib/ssh-keychain.dylib that traditionally has been used to add smartcard support to ssh by implementing PKCS11Provider interface. However since recently it also implements SecurityKeyProivder which supports loading keys directly from the secure enclave! SecurityKeyProvider is what is normally used to talk to FIDO2 devices (e.g. libfido2 can be used to talk to your Yubikey). However you can now use it to talk to your Secure Enclave instead!

How to Launch Hollywood on Windows, macOS or Linux

Install Docker Desktop.
Open a Terminal (Windows / Mac / Linux) and maximise it to the full size of your screen.
```
$ docker run --rm -it bcbcarl/hollywood
```
To exit: Try mashing Ctrl-D and Ctrl-C. If you get to a terminal you can type exit to close the container.

If this fails, just quit your terminal. 😁

Q: How do I combine individual video clips into one movie file for upload to YouTube using ffmpeg?

The following assumes you have ffmpeg installed on your Mac. If you need to install it, please use Homebrew.

The settings for encoding for YouTube with ffmpeg can be found here and here.

There is no error checking here. It assumes that there are videos in the folder, and that they have mp4 extensions.
