PCLCrypto by: Andrew Arnott

PCL Crypto provides a consistent, portable set of crypto APIs for .NET 4.5, Windows Store, Xamarin.iOS, Xamarin.Android. This makes it easier to create cross-platform .NET libraries and apps. Crypto functionality includes asymmetric and symmetric encryption and signatures, and key derivation. PCLCrypto calls into each native platform's crypto API for maximum performance. For RSA operations this produces a 2-100X improvement in performance on Android and iOS over using the standard RSACryptoServiceProvider API.
