HASH CRACKING
HASH
What is a Hash? Hash is actually the product of a hash encryption function ,
What is a better hash definition? A hash is a one-way math operation that is done on plain text to give us a fixed-size codec at the output. In previous posts we talked in detail about cryptography and hash functions.
One of the important uses of hashes is to encrypt or encrypt passwords
How did we create this coded text? Very simple. We provide plain text as an input to the program that performs the MD5 hash to create a coded hash product for us. There are two ways to create this hash: Hash tools in PC and Online
A hash function is any function that can be used to map data of arbitrary size to fixed-size values. The values returned by a hash function are called hash values, hash codes, digests, or simply hashes. The values are used to index a fixed-size table called a hash table. Use of a hash function to index a hash table is called hashing or "random-looking strings of characters into which the passwords have been mathematically transformed to prevent them from being misused. This transformation is called hashing "
Identifying Hash Algorithm
Before we start discussing about hash identification I want to tell you something real quick,
Hexadecimal Numbers: 0,1,2,3,4,5,6,7,8,9, a,b,c,d,e,f are called hexadecimal characters
Each hexadecimal number represent 4 bits. Now for example, the string "a26fe" contains 5 Hexadecimal characters
So I can say its a 4 x 5 = 20 bit string
It contains only hexadecimal numbers right? The number of characters in this hash is 32.
Hence the length of the hash in bits can be calculated as, 32 x 4 = 128 bits
MySQL database management system usually store passwords as MD5 hashes so I know its an MD5 and not a RIPEMD-128. Windows Use NTLM hashing algorithm, Linux use MD5, SHA-256 or SHA-512, Blowfish etc., Maria DBMS uses MD5 or SHA-1
Find the bit-length of the hash and write down possible hash types use your common sense to make an educated guess
List of bit-lengths of different hash types:
Name Length
MD2 128 bits
MD4 128 bits
MD5 128 bits
MD6 Up to 512 bits
RIPEMD-128 128 bits
RIPEMD-160 160 bits
RIPEMD-320 320 bits
SHA-1 160 bits
SHA-224 224 bits
SHA-256 256 bits
SHA-384 384 bits
SHA-512 512 bits
SHA-3 (originally known as Keccak) arbitrary
Tiger 192 bits
Whirlpool 512 bits
NTLM
&...
HASHING
Hashing is a method of encoding fixed-length data that performs encryption unilaterally and there is virtually no conventional method for decoding it. There are, of course, unusual ways to do this. For example, some sites have a large database of the most common words and phrases and their hash value. And if you give it a hash value, it will tell you the input value if it comes in the database.
The MD5 algorithm is one of the most widely used data hashing algorithms that can be used to ensure the accuracy of files and secure data storage.When hackers compromise a company to access its collection of users’ passwords, what they find and steal isn’t stored in a form that’s readable by humans at least if the company has even a pretense of security. Instead, the cache of passwords is often converted into a collection of cryptographic hashes
HASH CRACKING
In cryptanalysis and computer security, password cracking is the process of recovering passwords from data that have been stored in or transmitted by a computer system. A common approach (brute-force attack) is to repeatedly try guesses for the password and to check them against an available cryptographic hash of the password. The simplest way to crack a hash is to try first to guess the password. Each attempt is hashed and then is compared to the actual hashed value to see if they are the same.
Dictionary and brute-force attacks are the most common ways of guessing passwords. These techniques make use of a file that contains words, phrases, common passwords, and other strings that are likely to be used as a viable password .Most systems don’t store passwords on them. Instead they store hashes of passwords and when authentication takes place, the password is hashes and if the hashes match authentication is successful. Different systems store password hashes in different ways depending on the encryption used.Password hash cracking usually consists of taking a wordlist, hashing each word and comparing it against the hash you’re trying to crack. This is a variation of a dictionary attack because wordlists often are composed of not just dictionary words but also passwords from public password dumps. This type of cracking becomes difficult when hashes are salted
WE HAVE TWO METHOD FOR CRACKING HASH
First method is cracking hashes by Tools and second method is online cracking hashes by sites
