Has anyone used SecureBlackBox?

Has anyone used SecureBlackBox? It is a library that can be used with sockets to encrypt the data sent over the socket.

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.

If I strip out the library and just use normal sockets it takes from between 0.72 and 1.72 seconds.

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.

As mentioned below I can now see that two different types of sockets in the SecureBlackBox library are behaving differe开发者_运维百科ntly. On the client side if a TElSimpleSSLClient is used it is fast, but if a ElClientSSLSocket is used it is slow.

In both cases a ElServerSSLSocket is used on the server.

The license keys used in both cases are exactly the same.

Thanks.

Did you read the nag screen information? Evaluation key has delays that slow down operations. You can request the trial key which removes speed limitations.

Seems secure black box is a bit secretive about their sockets. Perhaps there are some bugs? Asking me to go to support, and not being straight up with me eh!
