NIST has chosen the Keccak algorithm as the new cryptographic hash standard but, in real life, many users are still waiting to move to its predecessor SHA-2. ... researchers were not content just to attack MD5. In 2005, Wang’s team improved known attacks on the SHA-1 standard, which was regarded as secure at the time. Although these attacks remain theoretical – nobody ...
