PHP SHA3 functionality

Question

Is there a framework or function that allows me to use SHA3-512? I don't want a extension like Strawbrary

Answer 1

For those coming to this later (after this post) PHP 7.1.0 has support for SHA3-512.

Answer 2

PHP 5.3.2 added SHA-256 and SHA-512 to the crypt() function. This might be somewhat similar to what your looking for

Answer 3

Yes sure simply you can use hash function in php

<?php
echo hash('sha3-512' , 'String you want to hash');

Answer 4

It's possible.

Maybe too late, but I've worked on a pure-PHP implementation here:

• SHA3-224/256/384/512
• SHAKE128/256 (arbitrary output size)
• LGPL 3+
• Works in PHP 5.2+ (considerably slower on older PHP)
• No extensions required.
• Moderately well tested.
• Based on the (public domain) reference implementation in C.
• Arbitrary input size.

It is a simple and fast implementation in PHP (which means far slower than C). Since this is purely "CPU-bound", PHP 7.0 runs 4x faster than PHP 5.6. (55kB/s here)

Fine with a small input. Correctly handles a huge input, just hogs CPU for minutes.

I hope it helps.
