PHP SHA3 functionality

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

Solution

  • 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.
