Welcome to the Keccak page! This page is dedicated to the cryptographic hash function family called Keccak, which we submit as a SHA-3 candidate. You can already find the complete specification and main document, software and hardware implementations, test vectors and results of the Monte-Carlo tests.

Although the Keccak specifications are frozen, we are still working on it actively to improve the analysis and implementation. We plan to publish a new version of the main document to describe the latest state of the analysis. Also, we are working on an improved software implementation, which we will publish the results soon. So please come visit us to get the latest news on Keccak, or better yet, subscribe to the news feed to receive automatically these news in your newsfeed reader.
