New submission from Gilles Van Assche <gilles-pyt...@noekeon.org>: Dear all,
I think it would be nice if hashlib would include the support of Keccak with a chosen suffix, as well as the fast instance KangarooTwelve (K12). 1) Currently, hashlib's interface for Keccak only supports the 6 instances of FIPS 202 (SHA3-* and SHAKE*). However, the instances in NIST SP 800-185 (cSHAKE, KMAC, …) use a different suffix and therefore cannot be instantiated on top of the aforementioned 6 instances. Instead, simply adding the suffix as an argument to the constructor would enable a user to instantiate plain Keccak (as in Ethereum) or the SP 800-185 instances. 2) K12 is an alternative hash function (and XOF) in the Keccak family. It is fast, parallelizable and it benefits directly from the cryptanalysis on the (unchanged) underlying permutation since 2008. This would be IMHO a valuable addition to hashlib. Among others, implementations of K12 can be found in the XKCP on GitHub. Kind regards, Gilles (co-designer of Keccak and K12) ---------- components: Library (Lib) messages: 361280 nosy: gvanas priority: normal severity: normal status: open title: Improve Keccak support in hashlib including KangarooTwelve type: enhancement versions: Python 3.9 _______________________________________ Python tracker <rep...@bugs.python.org> <https://bugs.python.org/issue39539> _______________________________________ _______________________________________________ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
