Dear Victor Duchovni,

I  knew what you speak as below,
I have added the CBC padding and Mac and record head, but besides these len,  
it still have 24 bytes is more. the 24 bytes is before the application data. 

my problem still can n't be fixed.

The TLS "record layer" uses a 5 byte header. The actual data
is extended with a MAC, and encrypted which often adds CBC padding.

You should not make any assumptions about the length of the encrypted
data on the wire, there may also be packets for renegotiation if the
client or server chooses to do that.
