Cryptography aficionados, say hello to a new hash algorithm backed by the National Institute for Standards and Technology (NIST). Dubbed Keccak (pronounced "catch-ack"), the secure hash algorithm, ...

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 ...

The National Institute of Standards and Technology (NIST) today announced the winner of its five-year competition to select a new cryptographic hash algorithm, one of the fundamental tools of modern ...

安全哈希算法（Secure Hash Algorithm，简称SHA）是一类广泛应用于信息安全领域的单向散列函数，主要用于配合数字签名标准（DSS）中的数字签名算法（DSA）以保障数据完整性与身份认证。该算法家族包含多种版本，如SHA-1、SHA-224、SHA-256、SHA-384以及SHA-512，均属于不 ...

At the Crypto 2004 conference in Santa Barbara, Calif., this week, researchers announced several weaknesses in common hash functions. These results, while mathematically significant, aren’t cause for ...

This standard specifies secure hash algorithms, SHA-1, SHA-224, SHA-256, SHA-384, SHA512, SHA-512/224 and SHA-512/256. All of the algorithms are iterative, one-way hash functions that can process a ...
