Can you explain to me, what do you mean by the "most unbreakable encryption"? Is there a specific type of encryption that is considered unbreakable by all current methods and technologies? Or are you asking about the encryption that is the most difficult to crack, given the current state of cryptography? And if so, which encryption technique would you consider to be the most challenging to break? Additionally, are there any factors that make certain encryption methods more secure than others, and if so, what are those factors?
