Franzen V3

In this release, the handling of Franzen encrypted files has evolved.

The implementation is based on the franzcri class.

Full details are available on the Wiki:
https://github.com/fcorbelli/zpaqfranz/wiki/Voodoo-encryption-Franzen

Files generated with this version are not compatible with the previous one.

The main improvement is the restoration of rsync-friendliness, i.e. the ability to safely use:

rsync --append

This feature is still under active development and not yet fully stabilized.
Several refinements are still missing (e.g. format autodetection), and the codebase is relatively complex (~5,000 LOC).

The "magic" support for full-file CRC32 has been removed.
Unfortunately, it cannot be maintained without significant additional complexity.
Reintroducing it is not a priority at the moment.

Currently, Franzen encryption is supported only for single full files, not multi-file archives.

New Command: franzen compare

A specialized comparison mode designed to be rsync-friendly.

It compares two files only up to the size of the smaller one.
This is useful for debugging and for verifying compatibility with rsync --append.

New Command: work fc

Performs a binary comparison between two files without using hashes.

New Command: work compare2

Compares substrings between two text files, typically file hashes from local and remote sources.

It behaves similarly to a combination of grep and diff.

Improvements to the tui Command

The Text User Interface has been improved.
It is not yet perfect, but more stable and usable.

Available views:

• Press t for tree view (similar to tree)
• Press l for standard list view

Improvements to the dir Command

Various fixes and sorting enhancements have been implemented.

New switch:

/tree

Displays output in a tree format.

When sorting by size, recursive directory size is now shown.

New Command: tree

Essentially equivalent to:

dir /tree

Reworked autotest Command

Internally refactored for better maintainability.

Added support for:

-franzen <password>

Example:

zpaqfranz autotest -all -to z:\prova -franzen pippo

In this mode, additional tests specific to Franzen encryption are executed.

New Flag: -memzero

Enables early wiping of sensitive Franzen data from memory.
