Hello Gulshan - Thank you for taking the time to reply.
Just to clarify, I do understand the cloud is purely the storage medium and not involved in any encryption process, and why my suggestion was that the Enpass app folder, the vault and attachment files be randomly named, before being uploaded to the cloud.
As you say, if a hacker gets access to the files, they would still require the master password. My thought is, if a hacker had no idea what the files were, in the first place, they are far more likely to be discarded or ignored. Currently, an Enpass app folder stands out, and its name tells the hacker the software used to create the files inside, making it more of a target.
Thanks for your time.
