encryption ?

Hello

I'm break the encryption in this manner and with
Encrypt text voluntarily in this way.

0123456789
9876543210
0000000000
= = = = = = = = = =

Encryption for each group of figures to try to find repetitions
Or other things which may put me on the track.

I do not understand this format:

|format = "{%08lx-%04x-%04x-%02x%02x-%02x%02x%02x%02x%02x%02x}"

DT0PE987A654C321


0040AA3D > 8D04C5 20A2440>LEA EAX,DWORD PTR DS:[EAX*8+44>;

Cases 3,4,5,6,7,8,9,A,B,C,D,E,F,10,11,12,13,14,15,16,17, 18 of switch 0040AA21

Hello

Thank you for your answer but I do not know anything and I'm looking on various forums and
Nobody can tell me what encryption?
.
This text comes from an encrypted electronic card-based and pic16f876 eeprom
24lc512.

The microcontroller saves 40 bytes of data and only the maximum
numeric characters. 0123456789.

But before it encrypts the data and that I am reading with a terminal
data are received crypts.


As encryption is obscured by characters, figures, letters of alphabet

I did tests with a time 00: 00 and the date 01/01 / 2000 and I made a
every minute backup, backup 00:00, 00:01,
00:02, 00:03, 00:04, 00:05, 00:06, 00:07, 00:08, 00:09, 00:10
In order to understand how the encryption is done, so + 1 each time
Even with very little data that is not obvious.

And I do not know how?

Here are links where you can download programs and screenshots.
