Описание
Cryptographic Hash Algorithms are the backbone of modern security systems as they are used in digital signatures, message authentication codes, and many other security applications to generate message digests. A Cryptographic Hash Function maps a message of any length into a fixed-length hash value, (aka message digest) which serves as the authenticator. Most of the Cryptographic hash algorithms have been broken that includes MD5 and SHA-0. SHA-1 has met many theoretical attacks lately that bring a major threat to SHA-2 and all the security applications that are using SHA-2. NIST announced cryptographic hash functions competition in 2007 for the next family of SHA i.e. SHA-3. The winning algorithm will be named "SHA-3", and will be added to the hash algorithms currently specified in the Federal Information Processing Standard (FIPS) 180-3, Secure Hash Standard. SHA-3 finalist algorithms were open for public comments for one year. My area of work is concentrated on BLAKE algorithm. ...
