The SHA-1 hashing algorithm has been ‘shattered’
Researchers from Google and CWI Amsterdam have created the first publicly known SHA-1 collision. SHA-1 is a hashing algorithm: it turns data of arbitrary size (such as a string of text, or a file) into a fixed-length string, with a number of cryptographic properties . Hash functions are ubiquitous in IT in general and security in…

How broken is SHA-1 really?
Earlier this month, I gave a talk entitled ” How Broken Is Our Crypto Really? ” at the RSA Conference in San Francisco. In the presentation, I looked at vulnerabilities found in cryptographic protocols and analysed the likeliness of these being exploited in practice. I spent a few minutes talking about SHA-1 and stated that…

Throwback Thursday: Hash Woes
Just last week, VB Editor Martijn Grooten addressed an audience at the RSA Conference in San Francisco on the topic of cryptographic protocols that have supposedly been broken in recent years, including the SHA-1 hash function which is considered all but broken. Back in 2004, the entire crypto community was abuzz with the astonishing news that a…
