Is the key entered identical to the one in the database? The system only authorizes access when both hash values match. The same input always generates the same hash value: only then can this value function as a checksum.Three aspects are decisive in encryption: At the end of the process, for example, a hash value of 128 bits always results. This summary value is usually a hexadecimal cipher with a fixed length, which does not depend on the length of the initial content. They all have one thing in common, however, and that is that the content to be encrypted is subjected to various algorithms until a hash value is finally generated. Since cryptographic hash functions began to be applied in encryption, algorithms have continued to evolve and standards that ten years ago were considered unassailable are now seen as serious security breaches. Hackers first try out all the passwords in the dictionary, which saves time, although, depending on the complexity of the passwords (length and type of characters), this process can take longer and consume more resources than expected. In these files, which circulate freely on the Internet, numerous passwords can be found that are either very popular or have already been intercepted in the past.

This method can be combined with so-called password “dictionaries”. This leads cybercriminals to resort to brute-force attacks, in which a computer program tries to “guess” the correct sequence of characters constituting the password for as long as it takes. Instead, online services use various cryptographic mechanisms to encrypt their users' passwords so that only a hash value (summary value) of the key appears in the databases.Įven if the originating cryptographic function is known, it is not possible to deduce the password from this hash value, because it is not possible to reconstruct the procedure in reverse.

When users of a platform set a password for their account, this sequence of characters does not appear in plain text in a database on some server, as it would not be secure: if he could find a way into it, a hacker would have a very easy time gaining access to all the accounts of a given user.įor eCommerce, online banking or online government services this would have fatal consequences. Today, passwords are no longer stored unencrypted - or so it is hoped.

So, in short, rainbow tables are created by precomputing the hash representation of passwords, and creating a lookup table to accelerate the process of checking for weak passwords.

Most rainbows tables can crack most, but not all, possible hashes. Though rainbow tables act as a database, they are more complex under the hood, relying on a time/memory trade-off to represent and recover passwords and hashes. Rainbow tables greatly speed up many types of password cracking attacks, often taking minutes to crack where other methods (such as dictionary, hybrid, and brute-force password cracking attempts) may take much longer. Rainbow TablesĪ rainbow table is a precomputed compilation of plaintexts and matching ciphertexts (typically passwords and their matching hashes). Several methods to break encryption include dictionary attacks, brute-force attacks, and rainbow tables. Anything less than that unlimited power and time will require chance and good investigative skills.
