- [Dependencies] - What is needed for the tool to work?
- [Similar tools] - What other tools are out there?
- [Activity] - When did the project start? Is is still actively being deployed?
- [How to install] - How do you compile it?
--- Note, using source code to acquire (e.g. git clone/svn checkout) can't be used - Also downloading from the head. Please use a "tag" or "release" version.

- [Name] - Zip Break / zipbrk
- [Version] - 2.1.1b (Master)
- [Homepage] - http://kat.sdf.org/
- [Download] - https://github.com/kvesel/zipbrk OR http://kat.sdf.org/zipbrk.c
- [Author] - kat will suffice
- [Licence] - as-is, free usage
- [Description] - It modifies zip files for various purposes to include bypassing anti-virus detection, bypassing e-mail filters, modifying the integrity checks, and encryption settings.
- [Dependencies] - a C compiler and supporting operating system
- [Similar tools] - same thing, multiple different file and author names (zipbrk and zipbrk2 are variants)
- [Activity] - 2004ish initial release, rereleased in in 2017 with 64-bit support, feature extensions, and included a working manpage
- [How to install] - gcc -o zipbrk zipbrk.c
- [How to use] -
zipbrk file.zip --encryption-unset
Change the encryption flag to show the zip is unencrypted (whether the contents are actually encrypted or not). In contrast, --encryption-set performs the opposite operation. The -e and -de flags alternatively be used.
zipbrk file.zip --xor-crc32
XOR the current CRC32 values for each file against a hash generated from a user-provided password. Most zip programs will fail to attempt in opening the zip file contents because it will believe the contents are damaged.
zipbrk file.zip --signature-spoof
Modify the magic number of the zip file so filters and other software will incorrectly assume the file is not a zip file format, and will fail to extract or check the contents.
zipbrk file.zip --zero-date --zero-time
Strips the date and time information from the archived files to assist in sanitising the zip file contents of some identifying information.
