Subject: John the Ripper binary packages
This is in fact nothing new for the list, but we would like to announce the
existence of John the Ripper compiled packages:
* git repository at https://github.com/openwall/john-packages
- there are a stable release (Jumbo 1), a rolling release [1], and a
development release;
- you can find packages:
- in PortableApp style: for Windows and Mac;
- in sandboxed style [2]: for Linux;
- a Canonical snap (the recommended), a flatpak and a Docker image
(the recommended method for use in the cloud ☁);
What these packages offer:
- the deployment process and scripts used are public and are evaluated by
Static Code Analyzers;
- the VM images used for the build are produced by leaders players, for
example, the disk image used in the Windows package build is created by the
Microsoft (Azure) team, the Mac X86 by the Circle Internet Services, Inc;
well known and very active in Asia;
- automatic virus scanned by VirusTotal;

Hardening:
- it's known [3] that `john` isn't to be used on untrusted inputs, but how
about use hardening with `john`?
- our Linux packages execute in a sandbox which limits the system
privileges so that if a malicious content manages exploits a vulnerability
to execute arbitrary code it will be unable to compromise the underlying OS.
- in addition, some packages use binary hardening techniques [4];
The packages and usage guidelines are available for use by the community at
https://github.com/openwall/john-packages.
We appreciate your input and feedback. Greetings everyone.
- [1] Rolling release, also known as rolling update or continuous delivery,
is a concept in software development of
frequently delivering updates to applications. This is in contrast to
a standard or point release.
- [2] In computer security, a sandbox is a security mechanism for
separating running programs, usually in an effort
to mitigate system failures and/or software vulnerabilities from
spreading.
- [3] https://github.com/openwall/john-packages/security/policy I think
magnum said this.
- [4] https://en.wikipedia.org/wiki/Hardening_(computing)

PS: the codefactor grade and log has not been updated yet. Probably some
authorization email is missing to be processed. Openwall will take care of
that shortly.
