This comes with many benefits such as: - Speed. In fact, in our testing, backup times are slashed to under a second for 100 notes in debug mode. This can be improved by reducing memory copying and enabling hardware AES and SIMD in `rustc` flags. - Auditability. We use audited cryptography libraries such as `ring` and `aes-gcm` which provide better security. - Predictability. Due to the lack of a runtime, boxing and unboxing, the speed is predictable reducing many attacks which depend on timing information. The libraries are made to be run in constant-time which further improves security. Todo: - [ ] Setup build scripts to use hardware AES and SIMD when available - [ ] Remove debug log statements I added for testing - [ ] Improve error checking on the rust side - [ ] Setup build scripts for other platforms like `Linux`, `iOS`, `Android` and `macOS`. Current scripts only integrate with `windows`. Signed-off-by: Akshit Garg <[email protected]>

This relies on a build script hack as `cargo-xcode` uses wrong triplets for iOS simulator on x86_64 hosts. Signed-off-by: Akshit Garg <[email protected]>

It still needs testing though Signed-off-by: Akshit Garg <[email protected]>
