An algorithm that transforms a given amount of data (the "message") into a fixed number of digits, known as the "hash," "digest" or "digital fingerprint." Hash functions are a fundamental component in ...

A new report from Ark Invest and Unchained says advances in quantum computing could eventually challenge Bitcoin's (CRYPTO:BTC), cryptography, though the threat remains distant for now. Quantum ...

In this chapter we will look at choosing and optimizing cryptographic algorithms, particularly for resource-constrained systems, such as embedded systems. We will look at various strategies for ...

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

The PKI industry recommends that every SHA-1 enabled PKI move to the vastly more secure SHA-2. Here's why and how. For the past two years, I’ve been busy helping Public Key Infrastructure (PKI) ...

Bitcoin uses the elliptic curve cryptography method called secp256k1, where the formula y 2 = x 3 + 7 (over the real numbers) ...

After nine years of research and competitions, the National Institute of Standards and Technology released the final version of its Secure Hash Algorithm-3 standard Wednesday. SHA-3 is a cryptographic ...

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 ...

Understand the crypto concepts behind the modern internet security infrastructure, from digital signatures and transport layer security to blockchains and Bitcoin. Cryptography grows ever more ...
