Windows based program to Encrypt/Decrypt and play audio files from audiocubes.
Audiocubes are cube like audio players with an integrated speaker, that will automatically play encrypted audio files when a RFID tag with the appropriate code is placed on top of the device. All devices seen so far use XOR encrypted audio files with a .smp extension.
- Encrypt or decrypt a single file.
- Encrypt or decrypt a complete directory.
- Play an encrypted audio file without need to decrypt it first.
- Generate .mct files for use with Mifare Classic Tools to write tags for Salvat/hachette and Migros cubes.
- Generate .csv files for use with NFC TagWriter by NXP to write tags for Lidl cubes.
- Encryption can be easily changed.
- An Hexadecimal key can be defined to be used in XOR bitwise operations
- Bit rotation can be specified to be applied before or after applying the XOR operation.
- Keys can be saved to and loaded from files to facilitate changing keys for different audiocubes.
- Languaje can be easily changed using .lan files.
- No instalation needed, just download Smp2Mp3.zip, unzip and run smp2mp3.exe
- Hachette / Salvat audio cube (blue and green version).
- Lidl Storyland
- Migros Storybox
- Faba box
- Luppa - La granja de Zenon
** Some .key files might not be included in the .zip downloadable file. They can be downloaded from the Keys directory in this repository.
Joaquim S. has a similar proyect that works on Python. In addition he has collected a lot of information regarding this kind of cubes. His project can be foud here: https://github.com/oyooyo/audiocube
- Marc D. from https://www.mikrocontroller.net/ for publishing the initial file encryption and RFID tag structure.
- Joachim S. for figuring out the encryption of the Lidl Storyland audio files.
- Cean D. for providing example files for figuring out the encryption for the green cubes (My first alphabet).
