The “Harvest Now, Decrypt Later” hacking strategy relies on the belief that the world is only a few years away from ...

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.

As the digital economy accelerates and data security becomes a global priority, VEST Labs has officially unveiled its breakthrough innovation — VEST Hash, a next-generation cryptographic hash ...

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, ...

According to André Dragosch, PhD (@Andre_Dragosch), Bitcoin leverages the SHA-256 cryptographic hash function, which is fundamental to its network security and resistance against double spending or ...

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.

What is the Q-Day prize? The Q-Day Prize is a challenge to make the Bitcoin network quantum resistant. On April 16, 2025, quantum computing-focused company Project 11 announced the “Q-Day Prize,” a ...

Your browser does not support the audio element. What is so special about it? Another cryptographic algorithm with a fancy name added to your list of things to ...
