airdrop-keychain-extractor

The airdrop-keychain-extractor tool enables the extraction of cryptographic secrets used in Apple AirDrop's authentication process, including the Apple ID validation record, certificate, and cryptographic key. Its primary use case is to facilitate the integration of these secrets with open AirDrop implementations like OpenDrop, allowing users to utilize AirDrop functionality for devices restricted to contacts-only mode. Notably, the tool requires disabling certain macOS security features for successful operation, and it produces essential output files necessary for performing authentication in the alternative implementation.
