Rainbow tables correct answers IEssentially, these types of password crackers work with precalculated hashes of all passwords available within a certain character space, be that a-z or a-zA-z or a-zA-Z0-9, etc. These files are called rainbow tables because they contain every letter combination "under the rainbow." They are particularly useful when trying to crack hashes Caesar cipher correct answers The method of cryptography in which someone chooses a number by which to shift each letter o...
