アメリカの国家安全保障局(NSA)によって開発された「SHA-2」は電子署名やブロックチェーンに応用される暗号学的ハッシュ関数の1つです。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 ...

A widely used cryptographic algorithm used to secure sensitive websites, software, and corporate servers is weak enough that well-financed criminals could crack it in the next six years, a ...

Bringing to a close a five-year selection process, the U.S. National Institute of Standards and Technology (NIST) has selected the successor to the encryption algorithm that is used today to secure ...

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 retire it ...

No it is not. Just webpages and browsers need to move to TLS 1.2. TLS 1.2 supports SHA-2 hashes. It's been around for years. I implemented a solution using it in a private EFT terminal implementation ...

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 retire it ...

The cryptography world has been buzzing with the news that researchers at Google and CWI Amsterdam have succeeded in successfully generating a 'hash collision' for two different documents using the ...

The US National Institute of Standards and Technology (NIST) has announced the phasing out of the secure hash algorithm (SHA)-1 in the federal government. The agency said it will stop using SHA-1 in ...

Google has initiated a process to revoke trust from any certificates that rely on the outdated SHA-1crytpographic hash algorithm. Google announced Friday it will begin the process of phasing out the ...
