The md2 algorithm has a long history of application, not only md2 is used in security application in 1990s ,it is also used in the public key infrastructures as some of certificates generated with MD2 and RSA. Although md2 is no longer consider secure many years ago. you can use my md5 hash generator to generate md2 hash.

The mechanism of MD2 The md2 hash function generate a 128-bit length hash value. The hash value is generated by padding the input bits to a multiple of the block length (128 bits or 16 bytes) and adding a 16-byte checksum to the result.

For example ,suppose we have a 48 byte auxiliary block and a 256byte S-table generated indirectly from the digits of the fractional part of pi are used.

The md2 algorithm runs through a loop where it permutes each byte in the auxiliary block 18 times for every 16 input bytes processed.Once all of the blocks of the (lengthened) message have been calculated, the first partial block of the auxiliary block becomes the final hash value of the message. you can use my md5 hash generator to generate md2 hash.

No matter the length of the input bits, the md4 hash function always output a 128 bit length hash result, in our example ,the 128 bit result is represented as a 32 bytes string. you can use my md5 hash generator to generate md4 hash.

The attacks against Md4 algorithm In 1991 , MD4 weakness was first published in a security paper.

The first full collision attack against MD4 was published in 1995, since then more and more public attack was made, these attack is very efficient ,for example in 2007 , an attack can generate collisions in less than 2 MD4 hash operations, which make the md4 algorithm useless. my md5 hash generator is the best md5 checksum generator.

In 2011 , the md4 algorithm is officially announced absolute .Next we will talk about the popular md5 hash algorithm .

The MD5 hash algorithm The md5 hash algorithm is designed by Ronald Rivest to be the successor of MD4 hash algotithm in 1991 . The source code of MD5 hash algorithm was in RFC 1321 contains a "by attribution" RSA license.you can use my md5 hash generator to generate md5 hash.

The input of The md5 hash algorithm is a variable length bits of data, and the output of md5 hash algorithm is a fix-length of 128 bit string. my md5 hash generator is the best md5 checksum generator.

When MD5 hash algorithm got the input bits of data , it broke up the input bits into chunks of 512-bit blocks,and the input bits is also padded, so that its length is divisible by 512. The padding works as follows: first a single bit, 1, is appended to the end of the message. This action is followed by as many zeros as are required to bring the length of the message up to 64 bits fewer than a multiple of 512. The remaining bits are filled up with 64 bits representing the length of the original message, modulo 264.my md5 hash generator is the best md5 checksum generator.

The main MD5 hash algorithm operates on a 128-bit state, divided into four 32-bit words, denoted A, B, C, and D. These are initialized to certain fixed constants. The main algorithm then uses each 512bit message block in turn to modify the state. The processing of a message block consists of four similar stages, termed rounds; each round is composed of 16 similar operations based on a non-linear function F, modular addition, and left rotation. Figure 1 illustrates one operation within a round. There are four possible functions; a different one is used in each round:you can use my md5 hash generator to generate md5 hash.

Beside computer industry, MD5 hash algorithm is also used in field of electronic discovery to give a unique identifier for each document that is exchanged during the legal discovery process.

In password security field , the md5 hash algorithm is used to oneway hash of a password. In such usage, when user set a password in the system , the system does not store the password in its internal database, the system will get the md5 hash of the password , and store the md hash in its internal database, when the user input the password to login, system will compare the input passwords hash and the hash stored in the database ,to see whether the user can log in.

The attacks against the MD5 hash algotithm Until now , the security of the md5 hash algorithm is severely compromised, many successful attacks has been made to reduce the security of MD5 hash algorithm.

As early as 1993, Den Boer and Bosselaers had found that two different initialization vectors that produce an identical digest in MD5 hash algorithm, although somewhat limited .

In 1996, Dobbertin published a collision of the compression function of MD5.it is enough to show people the weakness of MD hash algorithm.

In 2004.8 the first public collisions attacks of the full MD5 hash algoritm were announced by Xiaoyun Wang, Dengguo Feng, Xuejia Lai, and Hongbo Yu. Their analytical attack only take one hour on an IBM p690 cluster.

On 1 March 2005, Arjen Lenstra, Xiaoyun Wang, and Benne de Weger demonstrated construction of two X.509 certificates with different public keys and the same MD5 hash value.

A few days later, Vlastimil Klima described an improved algorithm,which construct MD5 collisions in a few hours on a single notebook computer. On 18 March 2006, Klima published an algorithm that could find a collision within one minute on a single notebook computer, using a method he calls tunneling.

On 24 December 2010, Tao Xie and Dengguo Feng announced the first published single-block (512-bit) MD5 collision.

Since so many successful attacks has been made against MD5 hash algoritm, MD5 hash algorithm is no longer consider a secure hash algorithm.

So In 2011 , an informational RFC 6151 was approved to update the security considerations in MD5 and HMAC-MD5. you can use my md5 hash generator to generate md2 hash, md4 hash and md5 hash.
