Extended PrivKey

[shayanb]

On the current coinos model, private keys are encrypted with the user's password and are saved in the same object (Hash Key: Hash Value) as the user.

db0/user/user:USERNAME

But on our model, we should save them in another table, not accessible for the user. How should be the encryption?

Suggested method: We can use an RSA generated set of keys to encrypt all the private keys with the RSA public key and keep the RSA private key secure, and we will be able to decrypt the private keys from the SuperAdmin view on the browser using the RSA private key.
In this case even with the full access to the SuperAdmin user (user/password or hacks) it's not possible to get the private keys.
