そのSHA-2の中でも特に使われているSHA-256でハッシュを生成するための計算プロセスがよくわかるサイト「Sha256 Algorithm Explained」を、Domingo Martin氏が ...

Google is encouraging businesses and security practitioners to utilize cryptographic hashes like SHA-256, a Secure Hash Algorithm which serves as the basis of the Bitcoin network’s proof of work ...

The SHA-256 hash algorithm used by Bitcoin Next, I'll discuss the hash function used in Bitcoin, which is based on a standard cryptographic hash function called SHA-256.

SHA (Secure Hash Algorithm) The basic idea behind a SHA function is to take data of a variable size and condense it into a fixed-size bit-string output. This concept is called hashing.

SAN FRANCISCO, Calif &#151 A team of three Chinese researchers have compromised the SHA-1 hashing algorithm at the core of many of today's mainstream security products. Top cryptographers said users ...

Since the goal of the new Advanced Encryption Standard (AES) is to offer, at its three cryptovariable sizes, 128, 192, and 256 bits of security, there is a need for companion hash algorithms which ...

SHA-2 is actually a set of cryptographic hash functions (SHA-224, SHA-256, SHA-384, SHA-512) in the MD (message digest) algorithm design.

Researchers have found a new way to attack the SHA-1 hashing algorithm, still used to sign almost one in three SSL certificates that secure major websites, making it more urgent than ever to ...

Rest-in-Peace SHA-1. Like all security controls, they are only valuable for a certain period of time. SHA-1, a legacy hashing algorithm once used heavily in secure web browsing, has outlived its ...
