please,
can you explain me why every mde are generated different from the previous?

Try this sequence:
1) Take a .mdb and generate the correspondig .mde
2) Rename the .mde
3) Generate one more time the .mde from the same .mdb
4) Analyze the binary contents of the two .mde, you'll see
they are completely different.

Any ideas?
thanks
 
No. The reason is that MDBs and MDEs contain unallocated buffers whose
content is determined by whatever was in RAM at the time. It is nothing
to do with "encryption" - in the proper sense (ie. the application of
RC4 and DES to the file content), or in the sense that I suspect you
are using it (ie. the translation of source code into a tokenized
form).

HTH,

Hmm, my answer to this seems to have disappeared; so here it is again.

"Encryption" is not the reason for what the OP has noticed. The reason
is, MDE (and MDB) files contain unallocated buffers whose content is
determined by whatever was in RAM at the time the file was created &
saved.

And, MDEs are not necessarily "encrypted". In an MDE, the source code
has been translated into a different (binary) form, but that is not
"encryption". It is "tokenization". Encryption is the application of an
encryption algorthim such as RC4 or DES to the file content.

HTH,
