I'm confused about how open source DRM can even be a thing. Presumably once you've obtained one of these client identity files, you can modify OpenWV to capture the decrypted / raw video to wherever you want?
It isn't, it's just an open source library to talk to the closed source Widevine plugin included with Chrome, or, in this case with keys illicitly obtained from a broken Google plugin that they haven't revoked yet.
There were some open source white box cryptography attempts fifteen or so years ago and they didn't work because of precisely what you say.
That's not true and wouldn't work on OpenBSD anyway (binaries are not compatible). The files you're copying from another device are just encryption keys.

OpenWV is implementing the decryption itself:

Thanks that makes more sense (and is also a bit disappointing!)
> If you want to use OpenWV, you must obtain an appropriate wvd file yourself, and copy it to /etc/openwv/widevine_device.wvd
Ah ok then.
