Huuummmm  i'm encrypting the fragment + mac +
padding length, this gives 37 bytes of data and 3 bytes more for 
padding, if i'm not wrong the correct padding is

	03 03 03

I have checked this on windows and seems to be correct.

And a final note from the Microsoft .NET Framework help:


The PKCS #7 padding string consists of a sequence of bytes, each of 
which is equal to the total number of padding bytes added. For example, 
if 24 bits (3 bytes) of padding need to be added, the padding string is 
"03 03 03".

I think this matches OK to the padding needed for a TLS implementation ( 
but can be that i'm, wrong :) )
