Question

Research the different hash algorithms (Message Digest, Secure Hash Algorithm, Whirlpool, and RIPEMD) and then create a table that compares them. Include the size of the hash, the number of rounds needed to create the hash, block size, who created it, from which previous hash it was derived, its strengths, and its weaknesses.

Answer 1

Hash algorithms or hash functions is a mathemtical function that converts one value (numeric) into another compressed value. The different types of cryptographics hash algorithms - Message Digest, Secure Hash Algorithm, Whirlpool, and RIPEMD are some of the more commonly used ones.

Function	Output size(Length of the output value in bytes)	Number of Rounds required	Block Size	Created By
Message Digest (MD5)	128	64	256	Ronald Rivest
Secure Hash (SHA)	512	24	576	National Security Agency( NSA)
RIPEMD	320	80	512	Hans Dobbertin Antoon Bosselaers
Whirlpool	512	10	512	Vincent Rijmen Paulo Barreto
