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

Quantum computers still look like lab toys: Racks of hardware, error-prone qubits and almost no real-world applications. Yet if you check the roadmaps of major layer-1 blockchains, a new priority now ...

In many network communications it is crucial to be able to authenticate both the contents and the origin of a message. Digital signatures based on public key schemas are used for such authentication.

Blockstream Research deploys post-quantum signature verification on Liquid mainnet, protecting real Bitcoin assets from future quantum computer attacks.

Attackers are recording, and sometimes forging, vast volumes of human communication. Some of this communication is protected by cryptographic systems such as the Rivest–Shamir–Adleman (RSA) system and ...

Security experts are warning that a security flaw has been found in a powerful data encryption algorithm, dubbed SHA-1, by a team of scientists from Shandong University in China. The three scientists ...

Cybersecurity researchers are warning that the foundations of digital trust are under strain as malware grows more adaptive, evasive and collaborative. In response, a team of Romanian scientists has ...
