How Rainbow Table Works

Objective: 

Given a hash, get back the hash key.

Naive Way: 

1. Too much space - Have all mappings between plaintext and hash key (almost impossible - too large space)

2. Too much time - Trying one by one plaintext and try mapping

Rainbow Table:

Compromise between Space and Time

1.       Find the correct chain – Using the last column

2.       Getting the plain text – Using the first column

3.       1 failed or 2 failed, try again

What if we use R rather than R1,R2,R3?

Regular Expression - replace group

I have a html
<a href="cc.ccs"/><a href="bb.ccs"/><a href="#"/>

I want to replace the non # href so that it become
<a href="my_cc.ccs"/><a href="my_bb.ccs"/><a href="#"/>

print re.sub(
r"href=\"([^#].*)\"", 
r"href=\"my_\g<1>",
r"<a href=\"my_cc.ccs\"/><a href=\"my_bb.ccs\"/><a href=\"#\"/>")
