Former NSA director opposes iOS backdoor, but leans towards FBI in iPhone unlock debate

"In this specific case, I'm trending toward the government, but I've got to tell you in general I oppose the government's effort, personified by FBI Director Jim [James] Comey," Hayden explained to USA Today. "Jim would like a back door available to American law enforcement in all devices globally. And, frankly, I think on balance that actually harms American safety and security, even though it might make Jim's job a bit easier in some specific circumstances."

In the case of an iPhone 5c belonging to dead San Bernardino shooter Syed Farook, the FBI is demanding that Apple remove the limit on passcode attempts for Farook's phone, rather than decrypt it. Comey has insisted that the agency's interest is limited in scope — Apple, however, has argued that giving the FBI a workaround would allow it and others to break into any iPhone, and is actively fighting the order.

Though he left the NSA in 2005, Hayden is responsible for establishing some of the mass surveillance apparatus that would later be exposed by people like former NSA contractor Edward Snowden, including a domestic phonecall database.

In the interview, Hayden argued that while mandatory backdoors would be extremely useful for the NSA and other intelligence agencies, the U.S. is a "safer, more secure nation" without them, since other parties would take advantage. The latter view has also been expressed by Cook.
