crackle

Crack and decrypt BLE encryption

Platforms: Linux · Last verified September 6, 2026

crackle exploits a flaw in the BLE pairing process that allows an attacker to guess or very quickly brute force the TK (Temporary Key). With the TK and other data collected from the pairing process, the STK (Short Term Key) and later the LTK (Long Term Key) can be collected.
