Hi everyone,

Being very unfamiliar with encryption and secure transmission I'm at a loss
of how to do this.

I need to get info from my system to a clients (with many such transactions
for different clients) securely.

My thinking is firstly to require all clients to provide a public digital
certificate, then when they request the data send something like.

<data_transmission>
  <key>
    AES key that has been encrypted with PGP using the public key
  </key>
  <data>
    data encrypted with AES using the un-encrypted key
  </data>
</data_transmission>

Then when the client recieves the data, they un-encrypt the key with their
private key, and then un-encrypt the data.

Firstly, is this approach secure?

If it is, does anyone know where I might find some kind of tutorial(s) that
would help me with implementation.

I don't even know what library to look in...

Thanx for any help.

Daniel
