The raspberry pi 3 doesn’t have the hardware crypto extensions for aarch64, at least going by cpuinfo. That’s bad news for using AES for disk encryption, because software implementations of AES are slow. But there’s a disk encryption algorithm that uses your pick of chacha12 or chacha20 for the bulk data encryption. These algorithms were designed to be better suited to software and simd implementations than AES, so they’re a lot faster on the pi.
