ZeroNet security

I wonder if we have the same issue as early Bitcoin-core days where people steal the wallet.dat because of plain text.
Should ZN have an encryption mechanism of the user.json and sites.json?
Here is a pywallet encryption function that could be easily inserted into ZN.

Review the referenced pywallet encryption function and inspect how ZeroNet handles user.json and sites.json. Clarify the encryption requirements and scope before implementation; done should mean an agreed mechanism protects the relevant data without preventing normal ZeroNet use.
