Digest::SHA3 is written in C for speed. If your platform lacks a C
compiler, perhaps you can find the module in a binary form compatible with
your particular processor and operating system.

The programming interface is easy to use: it's the same one found in CPAN's
the Digest manpage module. So, if your applications currently use the
Digest::SHA manpage and you'd prefer the newer flavor of the NIST standard,
it's a simple matter to convert them.

The interface provides two ways to calculate digests: all-at-once, or in
stages. To illustrate, the following short program computes the SHA3-256
digest of "hello world" using each approach:
