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, 55 out of 64 submissions to the SHA-3 competition are publicly known and available. 51 submissions have advanced to the first round. So far, 8 out of 51 first round candidates have been officially conceded broken or withdrawn by the designers.

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