| Name | State | Version | Description | Travis CI |
|---|---|---|---|---|
| master | Active | 2.x | Modern refactoring of 1.2 branch that includes more advanced features, improvements in code maintainability and readability, and the reduction of duplicate code. Compatibility layer provided for older versions. |  |
| dev | Active | 2.x | Latest development code |  |
| 1.2 | Stale | 1.x | Drop-in replacement for zlib's minizip that includes WinZip AES encryption, disk splitting, I/O buffering and some additional fixes. | |
| 1.1 | Stale | 1.x | Original minizip as of zlib 1.2.11. |
Minizip was originally developed by Gilles Vollant and had been contributed to by many people. As part of the zlib distribution, Mark Adler has maintained the original minizip project.
In 2006, I began working with the minizip project and started submitting bugs I found in the library to Gilles Vollant via e-mail. In 2010, I implemented some additional features like disk splitting, I/O buffering, and WinZip AES encryption. My continued work on the project necessitated setting up a public repository so I could share these and other improvements with the rest of the world. I have been maintaining and actively developing this fork of the library ever since. In 2017, I refactored and rewrote most of the code as version 2 because it had become difficult to maintain and code readability had suffered over the years.

Thanks to Gilles Vollant on which this work is originally based on.
Thanks go out to all the people who have taken the time to contribute code reviews, testing and/or patches. This project would not have been nearly as good without you.
The ZIP format was defined by Phil Katz of PKWARE.
