Not worth the liability. I’d rather the landfill and peace of mind than the money
That's the whole point of encrypted storage. There is no liability if you used a reasonable password.
Why not accept you have peace of mind and resell on eBay for parts?
Assuming you didn't use "password123" or something.
I don't think any cryptography has stood the test of time. It's unlikely anything today will survive post-quantum.
