hexinator (proprietary graphical hex editor with many features)
This is the free/demo version of hexinator from "https://hexinator.com/".
hexinator is a powerful hex editor and reverse-engineering tool with
many advanced features. It's commercial, closed source software. The demo
version will function as the full version for a 14-day evaluation period,
with an option to extend it for another 14 days. After that, only the
basic hex editing functions will work. To purchase the full version,
see the web site.
Be aware that hexinator 'phones home' to www.synalysis.net. It uses an
encrypted connection, so it's uncertain exactly what data it's sending to
the server. If this seems like a major security/privacy concern to you,
you should not install this software.
The SlackBuild author has not tested the 32-bit version of hexinator,
other than to verify that it creates a valid Slackware package. If it
doesn't work correctly, please contact the maintainer using the email
address in the hexinator.info file.
