crackle

Crack and decrypt Bluetooth Low Energy (BLE) encryption. More information: https://github.com/mikeryan/crackle.

• Check whether the recorded BLE communications contain the packets necessary for recovering temporary keys (TKs):

crackle -i {{path/to/input.pcap}}

• Use brute force to recover the TK of the recorded pairing events and use it to decrypt all subsequent communications:

crackle -i {{path/to/input.pcap}} -o {{path/to/decrypted.pcap}}

• Use the specified long-term key (LTK) to decrypt the recorded communication:

crackle -i {{path/to/input.pcap}} -o {{path/to/decrypted.pcap}} -l {{81b06facd90fe7a6e9bbd9cee59736a7}}
