This issue is about oocrypto being broken and not using AES on darwin/arm64. Most likely, this means that the way in which we're trying to pick up CPU features does not work. So, for example this measurement using the 3.15 release candidate uses TLS_AES_128_GCM_SHA256. Conversely, this measurement using the development branch uses TLS_CHACHA20_POLY1305_SHA256. We should probably stop using oocrypto until we understand why it's not working as intended and possibly consider reverting back to ooni/go instead.

Turns out x/sys/cpu currently lacks support for proper AES detection in Apple Silicon, and go gives priority to the chacha20 suite if it cannot detect hardware support on both sides. The fix is trivial: just hardcode AES=true for darwin/arm64, which is exactly what internal/cpu is doing. See the linked upstream issues in the MR for the whole discussion.

fix(Makefile): re-enable Android builds
4eb5c5b 
It turns out the problem described in ooni/probe#2122
only affects darwin/arm64, so we should be good to re-enable Android.

fix: add support for darwin/arm64
f4eef75 
This diff ensures we hardcode the capabilities of darwin/arm64.

While there, strive to make the packages naming slightly less confusing.

Reference issue: ooni/probe#2122.

Surpersedes (and draws from) #5.

I'm going to merge the fix at ooni/oocrypto#7, which is based on the previous diff by @ainghazal at ooni/oocrypto#5 and includes improvements in naming and documentation that should dispel some ambiguity that @ainghazal mentioned in private to me while we were discussing this issue.

fix: backport darwin/arm64 patches from main
24a810b 
This diff backports code to correctly handle darwin/arm64 from
`main` (see #7).

While there, this diff aims at reducing unnecessary differences with
the main branch, by removing code we also removed in there.

The reference issues are:

1. ooni/probe#2122

2. ooni/probe#2223

chore: use {go,oohttp,oocrypto} v1.18.5 (#872)
fe6d378 
* chore: use {go,oohttp,oocrypto} v1.18.5

This diff pins OONI to use go1.18.5 and oohttp and oocrypto at
go1.18.5 as the version of go with which we build releases.

The same codebase also works with go1.19 although this configuration
cannot include Psiphon (see ooni/probe#2222).

Closes ooni/probe#2223.

* fix: use [email protected]

This ensures we keep ooni/probe#2122 fixed.
