Grøstl hash function for PHP Version 0.1 Grøstl is a new cryptographic hash function designed in response to the Cryptographic Hash Algorithm Competition announced by NIST. Grøstl is one of the five finalists in the competition and it is a tweaked version of its predecessor called Grøstl-0, the original submission to the competition. The author of this extension was in no way involved in the development of the Grøstl hash function. The hash source code was taken directly from NIST submission package with a few minor variable name changes so that it would play nice with PHP. See the CREDITS section for more details. = INSTALLATION = You'll need to have the PHP 5 development package and a working build environment to compile this module. To compile and install: phpize ./configure --enable-groestl make sudo make install Then add the following to your php.ini file: extension=groestl.so = USAGE = Function Description: string groestl_hash(string $string [, int bit_length = 512]) Example: // Build a base-64 encoded hash $hash = base64_encode(groestl_hash('Hello, world.')); = CREDITS = The Grøstl team: Søren Steffen Thomsen, Martin Schläffer, Christian Rechberger, Florian Mendel, Krystian Matusiewicz, Lars R. Knudsen, Praveen Gauravaram PHP extension written by Bryan C. Geraghty <[email protected]> For more details, see: https://www.groestl.info/ https://csrc.nist.gov/groups/ST/hash/sha-3/Round3/submissions_rnd3.html = LICENSE = The SHA-3 Submission Requirements states: "Each submitted algorithm must be available worldwide on a royalty free basis during the period of the hash function competition." If the algorithm is selected as the winner of the competition, the following applies: "an irrevocable nonexclusive royalty-free license to practice the referenced algorithm, reference implementation or the optimized implementations" If the algorithm is not selected as the winner, the license will be determined by the team.
