Are the file creation and modification date really encrypted? Is it possible to modify them?

Hello everyone, a customer asks me if the dating of the Illustrator file is safe and reliable to understand if the file is exactly what he created on a specific date. In practice, the customer has seen a printed product identical to his, but sold by another competitor. He believes a competitor stole his file and wants to prove it's his.
In addition to comparing the artwork, it can also show this based on the file date in Illustrator's "file info..." menu?. When I asked Adobe this question in a chat, he confirmed that the metadata is encrypted. Are the creation date and modification date part of the metadata? Is it possible to modify them? Can anyone in your experience confirm this for me?
Thanks so much for an answer!

Do you think it can be done because the creation date is not encrypted as Adobe says? 

I mean the information in the "info file..." command of the Illustrator menu is not reliable?

Thanks a lot for your reply

Long and short: No. This data is not genuinely encrypted as the gazillion tools and services that crack protected PDFs prove. Unless you have a genuine hash file of your original or a byte-exact encrypted original none of this proves anything. And legally it's not admissible, anyway, unless authorized by the respective authorities and verified by certified experts. Same for your hardcopy prints. So overall your chances here are close to zero. Just write off your losses and move on.
