title: Has anyone used SecureBlackBox?
body: <p>Has anyone used SecureBlackBox? It is a library that can be used with sockets to encrypt the data sent over the socket.</p>
  
  <p>I have a project that uses it, and to send a packet of data which is around about 976Kb using the SecureBlackBox library it takes 12 seconds.</p>
  
  <p>If I strip out the library and just use normal sockets it takes from between 0.72 and 1.72 seconds.</p>
  
  <p>Anybody else seen anything similar? I am not sure I can understand why some encryption and decryption would slow it down so must. It is a show stopper, and the library will have to go if it is indeed causing that much slowdown.</p>
  
  <p>As mentioned below I can now see that two different types of sockets in the SecureBlackBox library are behaving differently. On the client side if a TElSimpleSSLClient is used it is fast, but if a ElClientSSLSocket is used it is slow.</p>
  
  <p>In both cases a ElServerSSLSocket is used on the server.</p>
  
  <p>The license keys used in both cases are exactly the same.</p>
  
  <p>Thanks.</p>
