{code:java}
Client-side:
 IN: data1, public RSA key
 OUT: key2, data2
  1. Generate Key1 at random
  2. Encrypt data1 with key1 by AES => data2
  3. Encrypt key1 with a public key of RSA => key2
  4. Send key2 and data2 over network (safe for leak)
 
Server-side:
 IN: key2, data2, private RSA key
 OUT: data1
  1. Decrypt key2 with a secret key of RSA => key1
  2. Decrypt data2 with key1 => data1{code}
