Data recovery companies ought to have the integrity to just say no to a job, if they cannot do it risk free. Trying and failing with the risk of damaging the original data could be very costly to the customer, even if they don't charge money - the customer's lost data could be priceless.
The challenges will be different. Flash loses its charge in 30 years, most disks are encrypted, and on-site physical backups are mostly a thing of the past. The source might survive in a cloud repo, but it'll either be tied up for legal reasons or deleted when the customer stops paying the bill. But storage is cheap and getting cheaper!
Encryption for 30 years ago? Trivially breakable with quantum
I wouldn't be so sure - quantum computers aren't nearly as effective for symmetric algorithms as they are for pre-quantum asymmetric algorithms.
I can't think of anything from 30 years ago that isn't just a joke today. The same will likely be true by 2050, quantum computing or not. I wonder how many people realise this?
Even if one disagrees with my certainty, I think people should still plan for the concept that there's a strong probability it will be so. Encryption is really not about preventing data exposure, but about delaying it.
Any other view regarding encryption means disappointment.
You are underestimating the exponential possibilities of keys.
>plus general vulnerabilities and weaknesses discovered, will ensure that anything encrypted today is easily readable in the future.
You can't just assume that there is always going to be new vulnerabilities that cause it to be broken. It ignores that people have improved at designing secure cryptography over time.
AES is only 3 years shy of 30.
If you used MD5 as a keystream generator I believe that would still be secure and that's 33 years old.
3DES is still pretty secure, isn't it? That's 44 years old.
As for today's data, there's always risk into the future but we've gotten better as making secure algorithms over time and avoiding quantum attacks seems to mostly be a matter of doubling key length.
