Math.random() is a PRNG, not a CSPRNG. An attacker who observes a few outputs can predict every future call. I found this exact pattern generating API keys in a 44K-star open-source codebase. Here is why it matters and the ESLint rule that catches it.

Shipped v10.6.12 and v10.6.13 together because the first one broke something. The main change is that long-term identity private keys now live inside Rust SecretBytes with ZeroizeOnDrop.…

cryptography and vibecoding is not a combination thats appealing to many. my code and my documentation dont seems to be to the "quality" as expected. so recently i post my project on vibecoding subs.…

Hello, I was wondering why SHA3 is considered more secure than SHA2. I also was wondering about Shake256 vs SHA3 as I’m implementing SLH-DSA for my application. Thanks. submitted by /u/silene0259 [link] [comments]

I'm deriving the session keys using Keccak/SHA3 by absorbing three(3) things: (1) the salt, (2) the common secret and (3) bits from a common key file. Normally, all three are concatenated and then padded, and the whole thing is absorbed.…

I understand that the Ed25519 variety of EdDSA uses SHA-512 for the random oracle H. Would replacing H with Keccak be provably secure? I'm in a situation where the systems are constrained in ROM and RAM.…

I've built a 4096-bit hash function called ci-sha4096 with an unusual property — every round constant is independently verifiable from first principles, derived from two orthogonal sources: K-constants from Ci = 85/27, a rational constant whose fractional…

Been digging into post quantum cryptography lately and why lattice based crypto feels convincing. I've noticed most people talk about quantum threats from a Grover perspective: “Quantum computers just search faster” “Security gets roughly cut in half”…

The Commodity Futures Trading Commission has now established a stance on how regulated U.S. firms can engage in crypto perpetual futures contracts.

For years, the most popular way to trade crypto — a never-expiring, highly leveraged contract called a perpetual future — has existed almost entirely beyond the reach of US regulators, thriving on offshore exchanges that operate outside American law.
