A powerful digital certificate that can be used to forge the identity of any website on the internet is in the hands of in international band of security researchers, thanks to a sophisticated attack on the ailing MD5 hash algorithm, a slip-up by Verisign, and about 200 PlayStation 3s.

"We can impersonate Amazon.com and you won't notice," says David Molnar, a computer science PhD candidate at UC Berkeley. "The padlock will be there and everything will look like it's a perfectly ordinary certificate."

At issue is the crypto technology used to ensure visitors to Amazon.com, for example, are actually connected to the online retailer and not to a fake site erected by a fraudster. That assurance comes from a digital certificate that's vouched for and digitally signed by a trusted authority like Verisign. The certificate is transmitted to a user's browser and automatically verified during SSL connections -- the high-security web links heralded by a locked-padlock icon in the browser.
