Hi again. I need help about decoding. The situation is: I have client and server

Server: 34,16741
Client: 48,148737082
48,3107146276

So the client is encoding the string, that is coming from "34,"(now it is 16741) and is sending 2 encoded strings. The first time is 148737082, and the second time is 3107146276.
Here is what NuMega Smartchek shows:

This is the encoding from first string. (I mean: 148737082)

This is the encoding from second string. ( I mean: 3107146276)

Everytime you run the executable the strings are different.
Do you have any ideas? Thank you.

It could be anything at all.... For example:
request: a random number generated from date/time
reply: the hash

Are you trying to remove some protection? Just have a look at the code that generates the request - you might be able to disable the check completely, without trying to understand the communication format.
