Apple believes encryption is the "single best tool we have to protect data and ultimately lives".
Th technology giant made the statement in a submission to the Australian government in response to some proposed changes of the country's encryption laws.
Apple also wrote in its submission: "Some suggest that ... access to encrypted data could be created just for only those sworn to uphold the public good.
"That is a false premise. Encryption is simply math. Any process that weakens the mathematical models that protect user data for anyone will by extension weaken the protections for everyone.
"It would be wrong to weaken security for millions of law-abiding customers in order to investigate the very few who pose a threat."
Meanwhile, Apple recently struck a deal to buy part of chip-maker Dialog for $300 million.
The acquisition includes some of the British company's patents and facilities, and will also see as many as 300 computer-chip engineers join the Apple team.
Following the announcement, Johny Srouji - Apple's senior vice president of Hardware Technologies - said: "Dialog has deep expertise in chip development, and we are thrilled to have this talented group of engineers who've long supported our products now working directly for Apple.
"Our relationship with Dialog goes all the way back to the early iPhones, and we look forward to continuing this long-standing relationship with them."
