Generating Authy passwords on other authenticators

---

*update: TBC, but this new might affect how easy it is to use this technique past August 2024: Authy is shutting down its desktop app | The 2FA app Authy will only be available on Android and iOS starting in August

---

This gist, based in part on a gist by Brian Hartvigsen, allows you to export from Authy your TOTP tokens you have stored there.
Those can be "standard" 6-digits / 30 secs tokens, or Authy's own version, the 7-digits / 10 secs tokens.

* Reducing executable size: 
http://developer.xamarin.com/guides/cross-platform/deployment,_testing,_and_metrics/memory_perf_best_practices/#Reducing_Executable_Size

* Use the linker (iOS [1],  Android [2]) to remove unnecessary code from your assemblies
[1] https://developer.xamarin.com/guides/ios/advanced_topics/linker
[2] https://developer.xamarin.com/guides/android/advanced_topics/linking

* Reference third-party libraries judiciously

* Applying constraints to generics may reduce app size, since less code would need to be included (haven’t verified this)

This is a quick guide to debug potential line ending weirdness.

Note: I've thrown a lot of concepts in here around Git data structures without going into depth. If there's things that are unclear or you'd like some more details, just leave a comment and I'll either reply or expand on this post accordingly...

What sort of weirdness am I referring to? Consider this commit: https://github.com/dalefrancis88/Windsor/commit/e2543e5573781c7ded83166932c9c415feef11c0

While it looks like a very large commit, the contents of the file are unchanged. But the diffs are very intimidating.
