Is there a fast Big Integer implementation for iOS? (cryptography needs)

iOS does not have any big integer APIs (there are various big integer subsystems used by the OS, but none of them have a public API available to third-party developers). There are various third-party libraries available for this, but I’ve not used any of them enough to give you a specific recommendation.

Seems that Safari offers SimpleCrypto. It has a BigInteger (or should have) one according to W3C.

What are your thoughts about leveraging this from a Xamarin/iOS app? Or a Mac App?

Ah, interesting. My previous response assumed that you were looking for a native API.

What are your thoughts about leveraging this …?

I don’t have any direct experience with Web Crypto API, so I can’t offer any input on that.
