Rainbow table tool5/28/2023 ![]() ![]() The fixed size was necessary to speed up the look-up. In version 2 the RBT has a fixed size of 1.25 TB even when only a single chain was added. For 99% success rate it required only a few hundred MB which fits on a single SSD. A look-up for an end-value-prefix needs multiple read accesses (binary search). Each time a chain was added it was merged with the RBT and sorted and the complete resulting RBT was written to disk. When adding the first chain the size is very small. RBT In version 1 the RBT has a variable size. The most are required to get the high speed in key look-up.

I don't know what success-rate a full RBT will have. If the community creates more chains and share it to others the success rate can be increased to maybe 90%. The fixed RBT size of 1.25 TB is still not full. It requires 1.25 TB and the success rate is currently 77.4%. ![]() It is able to do a key search in ~4 seconds on SSD (on HDD it takes 29 seconds). The version 2 was rewritten from base and the top design goal was speed. On HDD a key search takes nearly one hour and on SSD only some minutes on a RBT size of 200-300 MB. The version 1 of the tool was fast enough to break static BISS keys, but to slow for CAS systems. To speedup the things the tool will use the Graphics Processing Unit (GPU) on a video card from Nvidia to do the calculations necessary to create the RBT and also for the little post calculation during key look-ups. ![]() After the one time RBT creation was done it can be used for many key look-ups that are very fast. The CSA-Rainbow-Table-Tool is able to create a large database called Rainbow Table (RBT) based of these encrypted null packets which will take a long time. If the video bit-rate is lower than the required bit-rate mostly zeros are appended to the video packets before the stream gets encrypted. As base for video/audio encryption they also use CSA but the key changes every ~10 sec. The better systems use a Conditional Access System (CAS) like Conax, Cryptoworks, Nagravision, Seca, Viaccess, NDS Videoguard. The BISS encryption use a more or less static CSA key. CSA is used to encrypt the video and/or audio. Introduction Nearly all encrypted digital television programs transmitted via satellite are scrambled by the CSA algorithm.
