The SHA-3 Zoo (work in progress) is a collection of cryptographic hash functions (in alphabetical order) submitted to the [http://www.nist.gov/hash-competition SHA-3 contest] (see also [http://en.wikipedia.org/wiki/SHA-3 here]). It aims to provide an overview of design and cryptanalysis of all submissions. A list of all [[SHA-3 submitters]] is also available. For a software performance related overview, see [http://bench.cr.yp.to/ebash.html eBASH]. At a separate page, we also collect [[SHA-3_Hardware_Implementations | hardware implementation results]] of the candidates. Another categorization of the SHA-3 submissions can be found [http://eprint.iacr.org/2008/511.pdf here].

|+'''The SHA-3 Zoo, as a subset of the [http://ehash.iaik.tugraz.at/index.php/HashFunctionZoo Hash Function Zoo], is a collection of cryptographic hash functions (in alphabetical order) submitted to the SHA-3 contest'''
+
 
 +
The idea of the SHA-3 Zoo is to give a good overview of cryptanalytic results. We try to avoid additional judgement whether a submission is broken. The answer to this question is left to NIST. However, we categorize the cryptanalytic results by their impact from very theoretic to practical attacks. A detailed description is given in [[Cryptanalysis Categories]].
 +
 
 +
At this time, 56 out of 64 submissions to the SHA-3 competition are publicly known and available. 51 submissions have advanced to [http://csrc.nist.gov/groups/ST/hash/sha-3/Round1/index.html round 1], 14 submissions have made it into [http://csrc.nist.gov/groups/ST/hash/sha-3/Round2/index.html round 2] and 5 candidates have been selected for the [http://csrc.nist.gov/groups/ST/hash/sha-3/Round3/index.html final].
 +
 
 +
The following tables give a first impression on the cryptanalysis of the SHA-3 candidates. The tables only show the best known attack, more detailed results are collected at the individual hash function pages. A description of the main table is given [[Cryptanalysis_Categories#Main_Cryptanalysis_Table | here]].

The SHA-3 Zoo (work in progress) is a collection of cryptographic hash functions (in alphabetical order) submitted to the SHA-3 contest (see also here). It aims to provide an overview of design and cryptanalysis of all submissions. A list of all SHA-3 submitters is also available. For a software performance related overview, see eBASH. At a separate page, we also collect hardware implementation results of the candidates. Another categorization of the SHA-3 submissions can be found here.

The idea of the SHA-3 Zoo is to give a good overview of cryptanalytic results. We try to avoid additional judgement whether a submission is broken. The answer to this question is left to NIST. However, we categorize the cryptanalytic results by their impact from very theoretic to practical attacks. A detailed description is given in Cryptanalysis Categories.

At this time, 56 out of 64 submissions to the SHA-3 competition are publicly known and available. 51 submissions have advanced to round 1, 14 submissions have made it into round 2 and 5 candidates have been selected for the final.

The following tables give a first impression on the cryptanalysis of the SHA-3 candidates. The tables only show the best known attack, more detailed results are collected at the individual hash function pages. A description of the main table is given here.
