Verify Secure Scuttlebutt message signatures (in parallel).
How is this different to ssb-legacy-msg?
It's built on top of ssb-legacy-msg and ssb-legacy-msg-data but exposes a hopefully easier
api, and most importantly it lets you batch process a collection of messages.
Batch processing is good for two reasons:
- it means we can utilise multiple cores using rayon
- it means we can use the ed25519_dalek verify_batch function that takes advantage of processor SIMD instructions.
Benchmarking on a 2016 2 core i5 shows that batch processing with par_verify_messages is ~3.6 times faster than using verify_message
Benchmarking on Android on a One Plus 5T (8 core arm64) shows that batch processing with par_verify_messages is ~9.9 times faster than using verify_message!
Benchmarks can be run with cargo criterion.
