Bouncy Castle PCL

Support for .NET 4, WP 8 SL, WP 8.1, Windows 8, MonoTouch, MonoAndroid, Xamarin.iOS, Core CLR

IMPORTANT: The Serpent cipher as of 1.8.0 is incompatible with the behaviour of Serpent in earlier releases; it has been modified to conform to the standard byte-order interpretation for blocks (and keys). The previous behaviour is available from 1.8.0 as the "Tnepres" cipher. See BMA-52 for more information if this may affect you.
