DESCRIPTION:Cryptographic hashing has many uses in information security su
 ch as digital signature verification and identifying changes in data. Begi
 nning in the early 1990s\, the National Security Agency and the National I
 nstitute of Standards and Technology (NIST) have published cryptographic h
 ash standards which have been incorporated into security applications and 
 protocols globally. As theoretical or real-world attacks succeed against t
 he hash functions\, more are developed to strengthen the weaknesses of pre
 vious designs. NIST’s set of cryptographically secure hash algorithms no
 w contains three main hash functions (SHA-1\, SHA-2\, SHA-3) with addition
 al variations.\n\nIn this talk\, we will discuss what makes a hash algorit
 hm cryptographically secure\, how previous SHA algorithms have been compro
 mised\, the NIST competition hash competition to find a divergently-design
 ed hash algorithm\, and the SHA-3 algorithm that became a secure hashing s
 tandard after winning the competition.
