So how do we solve the problem of your DB encryption? We use Asymmetric
to encrypt the Symmetric keys. The 'heavy lifting' of encryption /
decryption of the data is actually handled by the AES cipher which is
relatively fast, and only the decryption of the AES keys is done with
the slower Asymmetric cipher.

Not sure if I quite follow that.

1. Data encrypted by AES key

2. AES key encrypted with Asymmetric public key (?)

3. AES key decrypted with Asymmetric private key (?)

4. Data decrypted by AES key

What have we achieved? The Asymmetric private key still has to be made
available.

I'm sure your previous post has the answer to this, but I can't quite
see it.
