How to crack a smartrider

Prerequisites

Easiest method for installing crypto1_crack is to install it via miLazyCracker and modifying the install script to replace broken packages.

Clone the miLazyCracker repository.
Download craptev1-v1.1.tar.xz and crapto1-v3.3.tar.xz from this repository and save them into the same folder as miLazyCrackerFreshInstall.sh.
Comment out lines 6 and 7 from miLazyCrackerFreshInstall.sh containing the wget commands.
Run miLazyCrackerFreshInstall.sh and the setup should proceed successfully.

Connect the NFC card reader and with your card on the reader, run mfoc -O dump.mfc
MFOC should find the key for Sector 1 Key A and use that to decrypt the rest of the card.
If that works, mfoc will print the card contents in the terminal and into dump.mfc. If MFOC says that the hardnested attack isn't supported, you must use the next method

Connect the NFC reader and place your card on the reader.
Run libnfc_crypto1_crack (key A) 0 A 0 B, replacing (key A) with the key. Use method 1 to find the key (you can find the key, but mfoc can't crack the newer cards). This will return your personal key A.
If the key is found, run libnfc_crypto1_crack FOUNDKEY 0 B 4 A, replacing FOUNDKEY with the key that step 2 outputs. This will return your personal key B.
Once you have both keys, paste them both into a file called keys.txt in your working directory, on individual lines.
Run mfoc -O dump.mfc -f keys.txt.
Assuming all goes well, the terminal will output the card contents to the terminal and into dump.mfc.
