Security researchers have achieved the first real-world collision attack against the SHA-1 hash function, producing two different PDF files with the same SHA-1 signature. This shows that the algorithm ...

A rainbow table is a large, precomputed table designed to cache the output of cryptographic hash functions to decrypt hashed passwords into plaintext. Rainbow tables were invented by IT expert ...

It isn't often that a decades-old assumption underpinning modern technology is overturned, but a recent paper based on the work of an undergraduate and his two co-authors has done just that.… That ...

For more than six years, the SHA1 cryptographic hash function underpinning Internet security has been at death’s door. Now it’s officially dead, thanks to the submission of the first known instance of ...
