# Proxmark3 v4.14434 Released

> A major MIFARE DESFire overhaul with full secure-channel support and new app/key commands, plus an HID Indala 4041X cloning fix, the `hf_reblay` relay standalone, and experimental macOS MacPorts builds.

_2021-09-18_

This is the "Crimson" release of the Iceman fork of the Proxmark3 firmware and client. Its centerpiece is a large rewrite of the MIFARE DESFire stack, alongside a corrected HID Indala cloning path and several new tools.

## Highlights
- Major MIFARE DESFire rework: native and secure channel handling for d40, EV1 plain, EV1 MAC, and EV1 encrypted modes, with CRC16/CRC32 and CMAC validation moved into a dedicated `desfirecrypto` module.
- New DESFire client commands including get UID, get and change key settings, get key version, free memory, format PICC, and application create and delete, exposed under `hf mfdes`.
- Added a `mfdes default` mechanism and `CLIGetOptionList` in the CLI parser so DESFire commands no longer require re-entering channel and key options each time.
- Fixed `getIndalaBits()` so HID Indala 4041X cards clone correctly: a read then clone with the same facility code and serial now produces an identical card.
- Added the `hf_reblay` standalone mode for relay attacks, along with supporting Python scripts.
- Added experimental macOS support for building with MacPorts in addition to Homebrew.
- Reworked MIFARE MAD handling: corrected the swapped application and cluster codes, added a JSON MAD directory lookup, and decode of the MAD info byte and cardholder information.
- Added default parameters for `hf cipurse` so you no longer need to supply them on every call, plus a fix for `hf 15 raw` that had broken the `hf_15_magic.lua` script.
