Edit report at https://bugs.php.net/bug.php?id=65891&edit=1 ID: 65891 Updated by: nikic@php.net Reported by: scott dot baker at gmail dot com Summary: PHP is missing a sha3() function -Status: Open +Status: Closed Type: Feature/Change Request Package: hash related Operating System: Linux PHP Version: 5.5.5RC1 -Assigned To: +Assigned To: nikic Block user comment: N Private report: N New Comment: The hash extension supports sha3 as of PHP 7.1, using the names sha3-224, sha3-256, sha3-384, sha3-512. Relevant commit: https://github.com/php/php-src/commit/d244b54c67cc2725283b78d4bb128501ae7910d3 Previous Comments: ------------------------------------------------------------------------ [2015-11-11 14:06:50] divinity76 at gmail dot com add it to the hash function and stop whining about sha3(), once its in the hash() it can _very_ easily be polyfilled if you want it. however, a slight problem is that sha3 is variable-length, so hash() needs to be modified to take a new argument of output size ------------------------------------------------------------------------ [2014-07-12 19:57:29] ryacko at gmail dot com Except that SHA-3 is a hash function with a variable length and variable security margin. One could add the four SHA3 standards, but that wouldn't make available all the possible ways to use SHA3. It could be used as stream cipher for instance. http://keccak.noekeon.org/tune.html ------------------------------------------------------------------------ [2013-10-15 17:18:29] nikic@php.net I agree with Pierre. This is a hash function, so it belongs in the hash extension. There is no point in adding an individual function for every single hash type. ------------------------------------------------------------------------ [2013-10-15 16:50:48] scott dot baker at gmail dot com Perhaps we could have support for both hash() and sha3() methods? I really like the sha3() method that strawbrary wrote. It's very logical and easy to remember. hash() requires me to remember the order of parameters, and the hash name. sha3() seems more direct. ------------------------------------------------------------------------ [2013-10-14 06:04:09] pajoye@php.net I would rather add it to the hash extension, more consistent. ------------------------------------------------------------------------ The remainder of the comments for this report are too long.
