Compare SHA-256 vs Keccak-256 cryptographic hash functions, security, performance, and blockchain applications.

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 ...

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 ...

Researchers have demonstrated new collision attacks against SHA-1 and MD5 implementations in TLS, IKE and SSH. If you’re hanging on to the theory that collision attacks against SHA-1 and MD5 aren’t ...

Imagine taking a block of data and turning it into a unique string of characters. Like giving it a digital nickname that never changes (unless the data does!). That’s a hash. Whether the original data ...

Chaotic hash functions represent a cutting‐edge convergence between nonlinear dynamics and cryptographic science. These functions employ chaotic maps—mathematical systems that exhibit extreme ...
