linux4eva Posted October 17, 2006 Share Posted October 17, 2006 Is it possible to append or update a rainbow table? For example, let's say I finish the configuration #0 example and have just alphabet characters as the charset. Is it possible to update it and add the numbers in instead of deleting and starting from scratch thus losing everything I've done? Quote Link to comment Share on other sites More sharing options...
linux4eva Posted October 17, 2006 Author Share Posted October 17, 2006 I was reading this: http://www.antsight.com/zsl/rainbowcrack/customcharset.htm Is there a difference between the uppercase and lowercase alphabet? Quote Link to comment Share on other sites More sharing options...
moonlit Posted October 17, 2006 Share Posted October 17, 2006 Yes there is. In computers the case matters a lot more than you might imagine. Humans see, for example, "a" as the same letter as "A". That's great but a computer doesn't relate those two characters at all unless told to, they are two different numbers and as such are totally different. Hope that helped, Moonlit Quote Link to comment Share on other sites More sharing options...
linux4eva Posted October 17, 2006 Author Share Posted October 17, 2006 So I would need to make a custom character set in order to create a rainbow table that stores upper and lower case as well as numbers? Thanks. Quote Link to comment Share on other sites More sharing options...
psychoaliendog Posted October 17, 2006 Share Posted October 17, 2006 well, lm hashes, the subStandard windows hashes, convert everything to upper case before hashing. So, there isn't a need to create hashes with lowercase characters it would be a waste. as for the original post, I don't think thats possible at least not with rainbow crack. Is it possible to write a program that allows that... sure... but it would take a lot of work to design a reduction function that allows for that.

linux4eva Posted October 17, 2006 Author Share Posted October 17, 2006 Well, I finished generating a very small table. Just uppercase letters for MD5 and tested it out and it seems to work quite well. Doesn't handle lowercase and numbers but I guess that will be next. ;) Quote Link to comment Share on other sites More sharing options...
