Re: how do I hide a variable from viewing

Todd,

I got tired of having clear-text passwords and other sensitive strings in my raku scripts, so I wrote KHPH for myself for use on Linux/UNIX, then published it.  The idea catches criticism because it isn't encryption, but rather just a little obfuscation.  Sometimes a little obfuscation is warranted, imo.

It takes a string, then mangles it into an unrecognizable scrambled form, stashes it in a file, then can be recalled/unscrambled later.

Maybe you'll find it useful, but maybe only on Linux/UNIX.

use KHPH;
KHPH.new(:stash-path('/tmp/.myapp/password.khph')).expose.print;


  *
or -

use KHPH;
my $passowrd = KHPH.new(:stash-path($*HOME ~ '/.rakucache/myapp/password.khph'));
# $password.expose will unscramble the string, so you can substitute it where you need to

Thanks,

Subject: how do I hide a variable from viewing

Hi All,

Fedora 41 (Linux)

Since my *.raku can be publicly read, how do I obscure
the contents of a variable so other can not read it?

Currently what I have been doing is setting the file's
ownership to root:root and the attributes to 700 so
only root can see it.

I would be nice to obscure a variable inside the
program though.

Many thanks,
-T
