Hi,

It's not necessary to look all the code, just if you need some more
data or want to run something in your computer... The question is that
in some cases (not all !!!) an std::string with encrypted values is
not sent entirely (through the Gio::Socket::send() &
Gio::Socket::receive() methods...). (hypothesis:) When the client
tries to decrypt this partial string throws an std::bad_alloc
exception instance (maybe, because it's, in fact, incomplete).

I haven't enough knowledge to find what happens inside this string, if
so. But in any cases, I need to ask you some help. Maybe, the
encryption routines are not the most appropiate. I choosen AES because
-as I know- is one of the most powerful symmetric encryption
algorithms.

Glus
