Epic cracking! - slayerdiangelo - 07-25-2017

Decades before,an epic hash cracking has took place and very few people know about it.To exploit the weakness of DES encryption,a community of people-known by the software they used to crack the DES algorithm "DESCHALL",took the world by storm-as they took only 4 months to crack the encryption which consisted of more than 4 quintillion combinations,even with the poor computing power of that time.

They achieved this goal by making use of Internet-by distributing their DRESCHALL client to anybody who is interested and who can afford an Internet connection and spare their valuable computing power.They distributed the key spaces through this client and made cracking faster.They managed to get more than 5000 clients from Canada and got an average speed of 3 TH/s,something which is available with an expense of a single GPU,these days!

Anyway,I just wanted to say that-if such a client is released these days,then even a 20 char long hash can be cracked within minutes,but nobody is interested, what to do?

Let me brake that down for you. Let's assume a 20-char hash of lower/upper/numbers. 62^20=7*10^35 combinations.
You want to crack that in 1 hour, than there must be ~2*10^32 tries every second.
A GTX1080Ti makes 4.6*10^10 hashes/s in MD5.

So you would need ~4 sextillion GPUs to do the job in one hour.

Strength in unity is what I wanted to convey,cracking a WPA hash in seconds would be far,far better than spending 2 or 3 hours to crack it on a stand-alone computer.

I guess most people would be very happy if they could crack WPA hashes in under a day. And anyone who has choosen such a weak hash has a bleak understanding of security. Even the 20-number-key of a standard router can be considered uncreakable under normal conditions.

nice story.. !! does hashcat offer a service deamon to donate part of the pc to the cloud help others ?? sorry i'm a complete noob.. jus trying to learn


RE: Epic cracking! - slayerdiangelo - 08-03-2017

No,it would be nice if they did so!

Cracking hashes would be a piece of cake,if they offered something like that.

Nope, it won't. Read my first post again and understand the math behind it.

What you're suggesting is simply wrong. That's not negative, that's a fact.
