Abstract: This paper introduces an enhanced lightweight image encryption method, combining a stream cipher and the Secure Hash Algorithm (SHA). The primary focus is developing a robust and efficient ...

Abstract: Recent years have seen extensive adoption of blockchain technology across a variety of application domains, all with the goal of enhancing data privacy, system trustworthiness, and security.

Melvo Baptiste is heading for the penthouse at APT 101 and it is a quiet flex. Raised on soul records rather than algorithms, ...

The system employs HMAC-SHA256 (Hash-based Message Authentication Code using SHA-256) for license integrity verification. SHA-256 refers to the Secure Hash Algorithm producing 256-bit hash values (see ...

Charles Edwards warns that quantum computing could depress Bitcoin price below $50,000 if the network does not address ...

In many technology-related discussions—especially those involving memory cards, CCTV footage, or forensic evidence—you may have heard the term “hash value.” While it sounds technical, a hash value ...

Microsoft is moving to disable RC4, an encryption cipher embedded in Windows authentication for more than two decades. The decision follows years of documented abuse, repeated warnings from security ...

Apple’s MacBook Pro uses custom Apple Silicon (M1–M4) chips integrating high-performance CPU, GPU, and Neural Engines. The Secure Enclave acts as a hardware coprocessor for key management and ...

Cisco routers utilize cryptographic features, such as IPsec VPNs, to secure network communications. IPsec combines encryption, hashing, and authentication for secure data transfer. Key components: ...

The X509_NAME_hash_ex method used by X509_issuer_name_hash and X509_subject_name_hash currently uses the SHA1 algorithm to generate the hash (and has since MD5 usage was deprecated long ago). However, ...
