China claims it cracked Apple's AirDrop encryption to identify senders and monitor 'inappropriate speech'

• A Chinese tech company claims to have cracked Apple's AirDrop encryption. 
• Chinese authorities say the information helped catch people sending "inappropriate information." 
• Government critics have used the app to send information wirelessly. 

Chinese officials claim a Beijing company has cracked Apple's AirDrop encryption, a development that could enable police to trace dissidents who've used the app to spread anti-government messages.

The company Wangshendongjian Technology was able to identify users by hacking encrypted device logs, according to China's Justice Bureau.
