Convergent encryption sounds great. But if Mega is using this, do they have any way of finding out which users have a specific file?
Example: Alice and Bob both upload the same file to Mega. Alice is raided by the MAFIAA. They get a court order telling Mega to list all users having a copy of that file. Can Mega comply? Or does not even Mega know that Bob has the same file too?
Related question: Is there any way for Bob to share his uploaded file with friends?
