Dictionary Attack cracking Hash code
What is Brute Force Cracking Attack?

 if you understand the clearly what is brute force and dictionary attack,actually no need to read this article.  but listing difference between them is good idea.
Brute ForceDictionary Attack
Use different kind of possible key combinationUse list of known passwords
large number of key combinationLimited to certain common keys
Time is depending on the password strong and lengthTime is depending on length of dictionary. i mean number of common passwords.
example of possible keys:
hello,HELLo,Eello,keLLO,FELlo,..
Example of common passwords:
iloveyou,12345,54321,ilovemom,ILOVEYOU...
Easy to crack when the key length is small Easy to crack if the password is common password

Conclusion:

First give trial to Dictionary attack. most of passwords will be cracked using dictionary attack itself.
If it is hard to crack the Hash code using dictionary attack,then go with Brute Force attack.

How to Crack the Hash Code using Dictionary Attack ?|Cracking Tutorials

In my previous posts, i have explained what  brute force attack is and how to implement using cain  tools.  Today i am going to explain what dictionary attack is.

Dictionary Cracking Method:

  This is second type of Cracking the cipher text.  Trying all known passwords is known as Dictionary attack.  Usually users will set simple password like 12345,54321,ilovemom,one4three,143,iloveyou.etc.


How to Crack the Hash Code using Dictionary Attack ?

   First of all store the possible passwords in a text file.  This file is known as Dictonary.

Algorithm:

Cracking Step 1:
Now get the password from the Dictionary as input and encrypt it.
Step 2:
Now the compare the created Hash code with original Hash code.
Step 3:
Case i:  if it is not equal then go to the step1 and follow the instructions
Case ii: if it equal then display the password.
Step 4:
What else you have successfully cracked the Hash code .  Enjoy.

CONCLUSION:

For Hackers:
you can try this Dictionary cracking method until  you know completely about the user.  Also sometime may set difiicult password like ae73kd3deo^ .  In this time you can not use this cracking method.  As you don't know about the password strength, you can try this method first.  If it fails to find,then go with Brute Force Attack.  

For Security needers:
If you really want to protect your account,then  set the password like iloveyou,ilovemom,12345.  Instead set a strong password so that hackers can not crack your password "easily".
