IntroductionIn February 2022, BlackBasta emerged as a successor to Conti ransomware and quickly rose to prominence. BlackBasta was operational for three years until February 2025 when their internal ...

Research suggests Bitcoin users could defend against future quantum attacks using a transaction design that works within ...

Google is dramatically shortening its readiness deadline for the arrival of Q Day, the point at which existing quantum computers can break public-key cryptography algorithms that secure decades’ worth ...

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.

Microsoft is shifting its stance on workplace collaboration from “optional safety” to “secure by default.” Beginning Jan. 12, 2026, the tech giant will automatically flip the switch on a trio of ...

I would like to ask whether it is possible in OP-TEE to use different algorithms for the main hash and the MGF1 hash in RSA OAEP. I would like to decrypt data using OP-TEE when the data was encrypted ...

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, ...

Oracle (NYSE:ORCL) shares were up 0.9% in premarket trading on optimism over the software company’s potential role in a TikTok deal. The technology firm would rebuild and secure a new U.S. version of ...
