This is kind of hypothetical, but let’s say I have a web app and I want to store a user’s email for sending notifications to.
Is there any zero-knowledge way to hide their email from ourselves and any potential database leaks while still having the ability to send to their address (which would obviously require the email plaintext?)
Alternatively, if there probably isn’t a way to hide it from ourselves is there any way to obfuscate the address in the database but still the user emails?
