For symmetric key generation we need to provide a password. What is the threat of using an universal password input for symmetric key generation in hybrid crypto systems and how should this be handled if following best practices?

I have a compliance question around crypto shredding and CCPA. I’m basically just wondering if crypto shredding is sufficient to comply with the CCPA customer deletion requests.
I know that crypto shredding has it’s own downsides (quantum computers??), but if data is only stored for a period of time (on the order of years), it seems reasonable to assume that crypto shredding keys that encrypt a specific user’s data will make that data inaccessible. Does this still count as deletion though from a legal perspective?
My question is specific to CCPA, but I’m also curious about crypto shredding in relation to laws requiring data erasure in general.
An example of an implementation of crypto shredding might be: – Create a unique key pair for each customer using the strongest encryption available at the time. – Encrypt all customer data with these keys. – Customer data may then be combined into large archival files (on tape or CD backup), with each record of a customer’s data being encrypted with their own specific keys. – A CCPA deletion request comes in, and we purge the key store of the decryption keys for that customer. – At this point we can no longer reasonably retrieve a customers data, even though it lives on archival media for a period of time. The only possible method of retrieval would be if decryption technology vast exceeded what we have available today.
I’m mainly looking for resources around the legal ramifications around this. My initial research shows that there are exceptions to archival storage of such data, but doesn’t have anything regarding crypto shredding. My current assumption is that since this isn’t theoretically permanent, it’s not a valid way to delete data according to the law.

I just wanna ask if is it more secure (rather than using windows 10 host) to use windows 10 in(VirtualBox), because before I’ve been installing crack software visiting a dangerous site (activation key something like that) but not that much but then today I formating my laptop but keeping my files (so I don’t know if some virus file or installed in my laptop has been deleted) but I deleted all unnecessary files in C drive and used ESET internet security to scan(deep scan) my laptop so right now there’s no crack software running into my laptop.
I used chrome for banking and crypto thing and there’s no installed extension and I don’t usually use it for daily search but firefox. I don’t know if it’s a good idea to used different browsers to avoid something like cookies, tracking, etc..
Virtualbox, I’m planning to install windows 7 or 10 or even Linux(I’m thinking of it since I don’t know about much in Linux) but the reason is for banking and crypto that’s all or vise versa I will use it for daily search visiting other sites that’s it.
what do you think? I will appreciate some advice 🙂 Thank you
These days cryptos are skyrocketing and a domain like this is a great opportunity.

This might be a very easy question. Let’s consider cryptograhic hash functions with the usual properties, weak and strong collision resistance and preimage resistance.
For any given output, obviously there are multiple inputs. But is that necessarily an infinite number of preimages, for any given hash value?
How would I go about giving a formal proof that there exists no crypto hash function h() such that there is a given value v = h(m*) for which the possible set of inputs m* is finite? Would this necessarily break collision resistance?
In S/Kademlia two crypto puzzles is used, one static and dynamic. The static is used to generate a key pair that makes an eclipse attack difficult to achieve, the dynamic to make Sybil attacks harder.
In the dynamic, I am very confused about the x which is found, since I can’t find any evidence for this ever being used again in the system, is it send along in a signature or what is it used to?
I do not think the paper mentions any use of it, I at least have not been able to find it, why I ask here for the use of x.
