Apple steps up encrytion to thwart police cracking of iPhones

Apple said Wednesday it was strengthening encryption on its iPhones to thwart police efforts to unlock handsets without legitimate authorization.

The move by Apple, the latest in an ongoing clash with law enforcement, comes amid reports of growing use of a tool known as GrayKey which can enable police to bypass iPhone security features.

Apple said the new features are not designed to frustrate law enforcement but prevent any bypassing of encryption by good or bad actors.
