How to analyse RBT table?

C

campag5242

Correct me if I am wrong, but aren‘t we talking about different approaches?
1. it is clear that only the first 8 bytes are the crypt8, therefore in principle you can have 2^64 different unique values (regardless of payload size, plaintype and cw)
2. for one single plaintype (payload size fixed) and 2^48 possible cw‘s you will have 2^48 crypt8 values
3. for one single cw (payload size fixed) and 2^(184*8) possible plaintypes you will have that high number of crypt8, e.g.
B8hx(184*00h)
B8hx(183*00h&01h)
B8hx(183*00h&02h)
...
B8hx(184*FFh)
Of course, there are a lot of duplicated values, ie one single cw might give us the same crypt8 using 2 different plaintypes
Yes, I now see we were talking about different things: I was restricting the term "Crypt8" to those useful types only ie those for which it is sensible to build tables. Specifically: those we have a chance to identify while in cyphertext (by high count, or any other means, which might give a clue re their plaintext couterparts).

-Crypt8 Calculator2 added
you can now calculate B8hx00h, B8hxFFh and B8hx03000h crypt8 values for cw's given in a txt.file

Any chance you can post a working LINK Please ?? :confused:
This link appears to be dead :(

Invalid URL - the link you are trying to access does not exist
The file has been deleted by the user.

Crypt8 Calculator2 was first included in RBTeditv2.4 and is now also included in RBTeditv2.5.
There is no stand-alone tool for Crypt8 Calculator2.

-Crypt8 Calculator and Crypt8 Calculator2 improved
no external library necessary anymore


-CW Lookup added
The procedure is as follows:
-create your database with the help of Crypt8 Calculator2 (e.g. use the CW_Brute_List from shishmish to create your database; it took 30min for me!)
-now select this database in CW Lookup and insert the C8 to be looked up


Thanks to shishmish for his great work!!!

PS: it is clear that this lookup table cannot replace Colibri's RainbowTables
