You might not have realized it, but the next great battle of cryptography began this month. It's not a political battle over export laws or key escrow or NSA eavesdropping, but an academic battle over ...

Security firm Mandiant has released a database that allows any administrative password protected by Microsoft’s NTLM.v1 hash ...

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 ...

How mining works is fascinating. When I explain it to people, I enjoy seeing their face the moment their mind is blown. I’ll explain it here, but just know, I’m imagining all your faces as your minds ...

Understanding Bitcoin is a one-way hash function should make sense because a hash function cannot be reversed. Once you understand that, it is hard to go back to thinking otherwise. The secure hash ...

The Tuesday updates for Internet Explorer and Microsoft Edge force those browsers to flag SSL/TLS certificates signed with the aging SHA-1 hashing function as insecure. The move follows similar ...

The SHA1 (Secure Hash Algorithm 1) cryptographic hash function is now officially dead and useless, after Google announced today the first ever successful collision attack. SHA1 is a cryptographic hash ...

Researchers have produced a collision in iOS’s built-in hash function, raising new concerns about Apple’s CSAM-scanning system — but Apple says the finding does not threaten the integrity of the ...

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 ...
