Supercomputer for Brute Forcing

[L0rd_M@dness]

I have access to one of the fastest super computers in the world.
Planning on Brute Forcing some hashes with it
Are there hashes that even supercomputer can't never crack?

[Kulverstukas]

Yes there are. I believe the same MD5 can be one, if the password behind the hash contains a lot or characters, including numbers and special symbols. Such can't be cracked... soon. I mean it would still be crackable, just it would take many years, even with a super computer

Because of how hashing works there's a chance that there's a much simpler plain text that results in the same hash!

It would also have to be properly salted.


The only (real) uncrackable method I've heard of is The One-Time Pad, if used properly. It's not so practical, but it is good.


I've also heard of rotating cleartext function, but no one has done that one yet (as long as I know).

You've read too much Dan Brown. There is no such thing as a "rotating cleartext"


@TS: I doubt you have "access to one of the fastest super computers in the world.". Even if you have access to some resources on some big grid, don't expect the world if you are just interesting in brute forcing random hashes.

First and second supercomputers in the world (until date):

FUCK YOU! XD. I put it there for fun. Now I feel like a moron XD.
::EDIT:: Now actually looking at it, there is such things.

It may be able to crack a significant amount of public and documented hashes but you have to keep in mind there are also plenty of custom algorithms that it couldn't. You would have to do that manually and those hashes may never be deciphered.

@wirelessdesert: yes, the one-time pad is the only truly uncrackable cipher. For that reason government messages to spies were encoded in such a manner, and its believed that Number stations transmit numbers, used with one-time pad.
Also that super computer is INSANE.

What I'm using it for right now is obviously not cracking hashes. I got access due to research purposes: [size=78%]http://www.tacc.utexas.edu/stampede/[/size]
But I thought it would be cool if I could also do cryptography on it. So... is this my wrong conclusion or does a supercomputer not make a huge difference when it comes to cracking hashes?

You really don't seem mature enough to be handling "one of the fastest supercomputers in the world".

Anyway, obviously the more powerful the hardware, the more TFLOPS (among other factors) and consequently higher throughput and calculation ability. Supercomputers tend to be used more for distributed projects or openly scientific ones, such as bioinformatics. Not to say cryptanalysis is out of the question, although feeble hash cracking is rather childish in comparison.

I don't understand what that has to do with anything. If your intentions are positive criticism, you can personally message your personal comments about me to myself. A public judgmental post is offensive to me since you consider yourself more intelligent than the professor who reviewed my proposal for using it and approved it. There are reasons, don't judge people simply by how they speak.
