# [KFDtool](https://github.com/KFDtool/KFDtool) Open Source P25 Key Fill Device Compliant with P25 standards (TIA-102.AACD-A) Purchase Hardware: [online store](https://kfdtool.com/store) Download Software: [latest release](https://github.com/KFDtool/KFDtool/releases) Release Notifications: [subscribe](https://kfdtool.com/newsletter) Demonstration: [video](https://www.youtube.com/watch?v=Oioa3xTQoE0) Software Manual: [view](doc/KFDtool_Manual.pdf) Security Considerations: [view](doc/SECURITY_CONSIDERATIONS.md) Features -------- **Key Fill Device (KFD)** The KFDtool software supports KFD features through the KFDtool hardware adapter (TWI/3WI/Three Wire Interface), as well as through a IP (UDP) connection (DLI/Data Link Independent interface). Keys and groups of keys can be saved to an AES-256 encrypted key container file, which can then be selected and loaded into a target device in one operation. Supported Manual Rekeying Features (TIA-102.AACD-A) * 2.3.1 Keyload * 2.3.2 Key Erase * 2.3.3 Erase All Keys * 2.3.4 View Key Info * 2.3.5 View Individual RSI * 2.3.6 Load Individual RSI * 2.3.7 View KMF RSI * 2.3.8 Load KMF RSI * 2.3.9 View MNP * 2.3.10 Load MNP * 2.3.11 View Keyset Info * 2.3.12 Activate Keyset Motorola refers to the P25 standard 3 wire interface (3WI) keyload protocol as ASTRO 25 mode or CKR mode. The legacy Motorola proprietary keyloading formats SECURENET and ASN (Advanced SECURENET) are **NOT** supported by KFDtool. PID mode is also used to refer to ASN mode. Key validators/generators are available for the following algorithms: * AES-256 (Algorithm ID 0x84) * DES-OFB (Algorithm ID 0x81) * DES-XL (Algorithm ID 0x9F) * ADP/RC4 (Algorithm ID 0xAA) **Mobile Radio (MR) Emulator** The KFDtool software only supports MR Emulator features through the KFDtool hardware adapter (TWI/3WI/Three Wire Interface) at this time. This mode allows another keyloader to be connected to the KFDtool, and the keys retrieved. Supported Manual Rekeying Features (TIA-102.AACD-A) * 2.3.1 Keyload Radio Compatibility ------------------- *Any statements of compatibility do not imply endorsement by the vendor. Testing has not been performed by the vendor themselves.* **A detailed list of compatible radios and adapters is available [here](doc/RADIO_COMPATIBILITY.md).** Radios that are compatible with Motorola KVL3000/KVL3000+/KVL4000/KVL5000 keyloaders in ASTRO 25 mode should be compatible with KFDtool. Keyloading cables made for other radios with MX (Motorola KVL) connectors can be modified by soldering an AC101 or AC102 Hirose pigtail in parallel with the MX connector according to [these](doc/MX_CONN_MOD_NOTES.md) instructions. Operations encapsulated with encryption (commonly referred to as FIPS mode) are not supported at this time for either the KFD or MR emulation modes. Hardware -------- Assembled and tested KFDtool hardware is available from me directly. I can ship internationally.

Note about hardware: I request that no one else manufactures identical or compatible units **and sells them to others while I am still doing so** - I have put quite a bit of my own money into developing this hardware. I am totally fine with someone making a unit for themselves or a couple of extras to give to their friends, just that they don't charge for them.
