How do rainbow tables work
WebBut how do rainbow tables actually work? Let's start at the beginning. What's a password hash? A very simple design for an authentication system is to store passwords in clear text, say, in a file named password.txt: hunter2 Cool bear's hot tip Don't do that. Obviously. Not in the 80s, and not in 2024. No, not even temporarily . Not even in logs. WebSep 10, 2015 · A rainbow table offers a mix between storing on-disk and computation by using chains. You would use less space than a full precomputed hash table, and it would probably be fine for short salts, but dealing with large salts would require a LOT of space. Here is an excellent site that describes the actual steps and gives examples for how it …
