Tweetable FIPS 202

19 August 2015

Very compact (or tweetable) implementations of Keccak, written by D. J. Bernstein, Peter Schwabe and Gilles, are now available. In their most compact form, the 6 instances of SHA-3 and SHAKE can fit in just 9 tweets.

Compact code implementing FIPS 202

We published a series of compact implementations, from the more readable one to the most compact one.

Dan presented the tweetable implementation at the rump session of Crypto 2015 [slides].
