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

At ETH Denver, developers warned that advances in quantum computing could threaten Bitcoin’s digital signatures as the industry continues to debate how to prepare.

In 2026, “provably fair” is no longer a bonus feature — it’s a baseline requirement for trust in crypto gambling. Provably ...

Hashing transforms data into a fixed-length cryptographic fingerprint that ensures integrity and authenticity. Every block in a blockchain contains its own hash and the previous block’s hash, forming ...

Abstract: The secure hash algorithm (SHA) is a widely used function for password hashing. This study introduced a modified SHA-512 algorithm by modifying the message scheduling, hash construction, and ...

In the realm of computer science, it’s hard to go too far without encountering hashing or hash functions. The concept appears throughout security, from encryption to password storage to crypto, and ...

Abstract: The reason learning-based hashing algorithms are "warm subjects" is that they are significantly expanding the size at which existing techniques work. In this research, we introduce a novel ...

Gravatar officially supports sha256 as its email hashing algorithm in mid-2024. It now suggests using sha256 as its email hashing algorithm to avoid hash collisions and privacy concerns.
