	md5crk: new DC project (http://www.md5crk.com) - Topic Ars OpenForum
		The aim of MD5CRK is to raise awareness in the IT industry that MD5 is not secure for many applications.
		Hopefully this will all be explained better on the md5crk site in the future, but for now, the van Oorschot paper is a good place to start.
		I've updated MD5CRK.com's How will MD5CRK show MD5 is insecure page to include screen captures from windows netscape and IE when I went to www.paypal.com.

		While Wang et al's attack was analytical, the size of the hash — 128 bits — is small enough to contemplate a brute force birthday attack.
		MD5CRK was a distributed project started in March 2004 with the aim of demonstrating that MD5 is insecure by finding a collision using a brute force attack, although it was ended shortly after Wang et al's announcement.
		Because of the discovery of an easy method for generating collisions, many researchers recommend that replacement algorithms, such as SHA-1 or RIPEMD-160, be used instead of MD5.

		There are a few other clients that also doesn't run at the lowest priority and I personally avoid all clients that isn't capable of running at the lowest priority and I know there are lots of other people that does the same, especially people with work farms.
		A new version of the MD5CRK client has been released (v1.0.5) which has better support for offline clients, install programs for Windows, and the client can now be installed as a service in Windows.
		MD5CRK will show empirically that MD5 is cryptographically insecure, and while some uses of MD5 need not be cryptographically secure there are many implementations currently in wide use (most notably signing SSL certificates) that require more than what MD5 offers.

	DC - Recently Completed Projects
		MD5CRK attempted to prove that the MD5 encryption algorithm is insecure by finding a collision: two inputs which can produce the same digest (encryption method).
		Researchers in China (not associated with MD5CRK) announced on August 17, 2004 that they found a collision (see their paper) and proved that MD5 can be broken in a matter of hours.
		MD5CRK was the first project to enable website owners to configure their web pages to link to a MD5CRK distributed Java applet.

	FX Claim MD5CRK
		This claim will be judged True if MD5CRK (www.md5crk.com) finds a collision in the outputs of the MD5 hash algorithm before 1 April 2006.
		The price of this claim will therefore track whether the project will be able to live up to that expectation, giving it one month extra.
		Judgement will be based on whether or not the MD5CRK project claims to be successful in their effort to find a collision in outputs of the MD5 hash algorithm using distributed computing (or a "Chinese Lottery").

		The size of the hash — 128 bits — is small enough to contemplate a brute force birthday attack.
		MD5CRK was a distributed project started in March 2004 with the aim of demonstrating that MD5 is practically insecure by finding a collision using a brute force attack.
		However, MD5CRK ended shortly after 17 August, 2004, when collisions for the full MD5 were announced by Xiaoyun Wang, Dengguo Feng, Xuejia Lai and Hongbo Yu [1] (http://eprint.iacr.org/2004/199.pdf) [2] (http://eprint.iacr.org/2004/264.pdf).

		On the cryptography front, Chinese researchers Xiaoyun Wang, Dengguo Feng, Xuejia Lai, and Hongbo Yu announced this week their discovery [57KB PDF] of a relatively simple method for generating MD5 collisions, demonstrating such collisions for the MD5, MD4, HAVAL-128, and RIPEMD-128 hashing algorithms.
		On hearing the news, MD5CRK announced that their project (which had been running for about 6 months and had reached 3,824 Million MD5 transforms per second) would be shut down within 48 hours: thank you, drive through.
		The MD5 hash (see RFC1321 for implementation details) is a one-way function that is used (in conjunction with public-key cryptosystems such as RSA) to establish a secure connection almost every time you purchase something online or log into your bank's webpage.

		As the MD5crk folks say, MD5 is widely used to authenticate financial transactions.
		I am minded too of the crack someone (Schneier?) published on Roger Needham's TEA cipher shortly after TEA was released; this required the availability of a totally impractical number of plain-texts.
		So the bottom line is that I cannot see that the point to which the md5crk folk drive is of great significance.

	Educated Guesswork: March 2004 Archives
		MD5CRK is a unique distributed attack in that it attacks one of the most actively used crypto-related algorithm and will provide loads of data for crypto research.
		The MD5CRK guys argue that collisions are a threat to the certificate infrastructure.
		The MD5CRK guys don't really explain the other attacks they think collisions might enable, so I can't evaluate those claims for sur, but in most cases the security of hash-based systems, depends on irreversibility, not collision resistance.

		The project aimed to disprove one of the fundamental requirements of a secure message digest: No two inputs can be found which produce the same digest - this is also known as a collision.
		On the 17th of August, MD5CRK announced the project would be closing due to a monumental discovery by researchers in China, who have found a collision in the full MD5 hash function.
		Here are the files you can use to verify their discovery: md5col.zip

		I've been doing a lot of reading lately, and although the commercial side of computing has decided that 128-bit MD5 is enough for their needs, the academic community is not really that sure.
		I've seen things like the MD5CRK project [http://www.md5crk.com/], which try to find collisions in MD5 out of completely different meaning (but still legible) text.
		Then there's also the classic man-in-the-middle and birthday theoretical attacks, but I've still to see any real life examples of one of these attacks.
