How do chains work in Rainbow tables?

around this issue Knowing the start point for a hash chain, you can compute all the intermediates and the end-point by repeatedly applying the hash-and-reduce function.
The end point comes in when you want to search the chain for a hashed password. Apply hash-and-reduce up to the chain-length number of times; at each stage, look to see if your intermediate matches the endpoint of any chain that you have computed. If so, then you've found the chain that includes the password. You then know where the chain starts because you've stored its start point, and so you can trivially walk forwards through the chain from there to find the password which, when hashed once, yields the hash value.

I hope this helps you . You should use bcrypt, which has been designed by professional cryptographers to do exactly what you're looking for.
In general, you should never invent your own encryption / hashing schemes.

hop of those help? A rainbow table is an optimization for inverting hash functions: finding the password when all you have is its hash. Although this is not strictly necessary here, I recommend reading What are rainbow tables and how are they used? which has a very good explanation that clears a few common misconceptions.
There are two parts to RAR encryption (or just about anything that uses a password to encrypt some data). First, an encryption key is derived from the password, using a key derivation function (KDF). Then the encryption key is used to encrypt or decrypt the data.

wish helps you The purpose of rainbow tables isn't to necessarily be faster but to reduce space. Rainbow tables trade speed for size.
Storing hashes for all possible 10 digit passwords for example would be prohibitively expensive in terms of disk space. Also you need to consider that since the dictionary space is so large it will require significant paging (very slow operation).

hop of those help? A rainbow table is "just" a smart compression method for a big table of precomputed hashes. The idea is that the table can "invert" a hash output if and only if a corresponding input was considered during the table construction.
Each table line ("chain") is a sequence of hash function invocations. The trick is that each input is computed deterministically from the previous output in the chain, so that:

seems to work fine it depends on the character ranges used, but 10 characters seems to be the limit in the the downloads here (lower for full character ranges).
