This module calculates the RadioGatún[32] sum for a given string, returning it in a format suitable for showing a demonstration sum on a Wikipedia page. RadioGatún is a cryptographic hash function from 2006 which remains, as of 2022, unbroken.
To use:
<nowiki>{{</nowiki>#invoke:RadioGatun32|''rg32''|''String to input''<nowiki>}}</nowiki>
Or with the template (at):
<nowiki>{{</nowiki>RadioGatun32|''String to input''<nowiki>}}</nowiki>
If there is {{Background color|#888|d}} in the string to input, the calculated sum will be based on a string without the background color formatting.
It is also possible to show the raw hexadecimal RadioGatun[32] sum of a given string without any formatting:
<nowiki>{{#invoke:RadioGatun32|rg32sum|</nowiki>''String to input''<nowiki>}}</nowiki>
For example, if we run:
<nowiki>{{#invoke:RadioGatun32|rg32sum|1234}}</nowiki>
We will get this:
This should output "9EBDD24F469993796C4AAC6A821735A65A3CDEF8A359944CE71F34E7A08E1182".
<nowiki>{{</nowiki>#invoke:RadioGatun32|rg32|Hello, world<nowiki>}}</nowiki>
Will create this output:
RadioGatun[32]("Hello, world") = D91BBD22BE5D01F091F26A16704CDA0E165588E025D9BA6619C5B01550756349
Here is the computed output:
We can have background colors:
<nowiki>{{</nowiki>#invoke:RadioGatun32|rg32|<nowiki>{{</nowiki>Background color|#ff8cc0|Li<nowiki>}}{{</nowiki>Background color|#c08dff|fe<nowiki>}}!}}</nowiki>
Shows us this:
The above should look exactly like this:
RadioGatun[32]("!") = 80E706E851DCDE1170452EEC6EAD24F40E63B9A07B86D8D32053A1237835E03D
The computed sum will be for the string Life!, as can be seen in the following:
The above should look like this:
RadioGatun[32]("Life!") = 80E706E851DCDE1170452EEC6EAD24F40E63B9A07B86D8D32053A1237835E03D
The background colors do not affect the computed RadioGatun[32] sum.
To test this in Mediawiki, go to, and verify that one sees "All RadioGatun[32] test vectors pass". One can rerun the test by going to, clicking on "edit this page", then in the debug console at the bottom, typing in print(p.test). One should then see "All RadioGatun[32] test vectors pass".
Another way to test this is to add <nowiki>{{#invoke:RadioGatun32/testcases|test}}</nowiki> to a page; wherever RadioGatun32/test is invoked, it should show "All RadioGatun[32] test vectors pass".
This module can either be run as a Mediawiki Lua module, or as a standalone Lua script. This very same script is also available on GitHub in a repo which includes automated tests to ensure implementations of RadioGatun[32] generate correct hashes against a number of test inputs, including all official RadioGatun[32] test vectors.
To test this code, in a *NIX compatible environment like Linux, with Git and a version of Lua above 5.1 and below 5.4 (Lua 5.4 dropped bit32; a Lua 5.1 implementation with bit32 support will also work), do the following:
git clone https://github.com/samboy/rg32hash cd rg32hash/sqa ./do.test.sh ../Lua/rg32wiki.sh
