Birthday attacks exploit the collision probability of hash functions. Collision resistance requires sufficiently large hash outputs. Modern blockchains use 256-bit hashes to mitigate collision risks.

Microsoft is shifting its stance on workplace collaboration from “optional safety” to “secure by default.” Beginning Jan. 12, 2026, the tech giant will automatically flip the switch on a trio of ...

Craving crispy, golden hash browns? 🥔 In this video, I’ll show you the easiest way to make perfect hash browns—using both the grill and fry methods for that ultimate crunch. A breakfast game-changer!

I would like to ask whether it is possible in OP-TEE to use different algorithms for the main hash and the MGF1 hash in RSA OAEP. I would like to decrypt data using OP-TEE when the data was encrypted ...

Cryptography secures communication in banking, messaging, and blockchain. Good algorithms (AES, RSA, ECC, SHA-2/3, ChaCha20) are secure, efficient, and widely trusted. Bad algorithms (DES, MD5, SHA-1, ...

Technology company Oracle will provide security for the new TikTok entity in the United States, following the President Trump-backed deal to allow the social media company to keep operating in the U.S ...

Two former Google DeepMind researchers who worked on the company’s Nobel Prize-winning AlphaFold protein structure prediction AI as well as its AlphaEvolve code generation system have launched a new ...

While the dawn of quantum computing may still be years away, federal agencies are facing a future threat that has already arrived. Adversaries are actively stealing encrypted government information ...

Blake3 is not listed as secure hashing algorithm in NIST SP 800-140Cr2 and therefore not FIPS 140 compliant. It's not clear if the choice and properties of the hashing algorithm is security relevant.
