In one of my previous post i wrote about the Basics of Password cracking In this tutorial i will teach you how you can crack Router passwords by using a dictionary attack .
What is a Dictionary Attack ?
An attack that tries all the phrases or words in a dictionary, trying to crack a password or key .A dictionary password cracker simply takes a list of dictionary words, and one at a time encrypts them to see if they encrypt to the one way hash from the system. If the hashes are equal, the password is considered cracked, and the word tried from the dictionary list is the password.

Secure Sockets Layer (SSL) is the most widely used technology for providing a secure communication between the web client and the web server. Most of us are familiar with many sites such as Gmail, Yahoo etc. using https protocol in their login pages. When we see this, we may wonder what’s the difference between http and https. In simple words HTTP protocol is used for standard communication between the Web server and the client. HTTPS is used for a SECURE communication.

What Is a Hash?
Ok, firstly alot of you still believe that hashes can be "decrypted", this is a common misconception because hashes are generated by One Way Cryptographic Hash Algorithms these means the algorithm that created them CAN NOT be reversed to determine the plain text password.
These one way functions are used by computers to prevent storing passwords in plain text in memory, instead when a password is entered (for example at a log in screen) a one way hash algorithm is applied to the supplied password and then the hashed output is compared to the hash for that user, stored in memory. If the two hashes match, the passwords are the same and the user is authenticated, if the two hashes are not the same the passwords do not match and the user is denied access.

In this post I will explain you about one of my favorite and interesting cryptographic algorithm called MD5 (Message-Digest algorithm 5). This algorithm is mainly used to perform file integrity checks under most circumstances. Here I will not jump into the technical aspects of this algorithm, rather will tell you about how to make use of this algorithm in your daily life. Before I tell you about how to use MD5, I would like to share one of my recent experience which made me start using MD5 algorithm.
