Crypto Recipes

Introduction

Most of the API is modeled after the WinRT crypto API. If you're familiar with that, you'll immediately feel at home with PCLCrypto. Instead of reusing the Windows.Security.Cryptography namespace, PCLCrypto functionality is available through the PCLCrypto.WinRTCrypto class.

In some cases, a .NET Framework API is emulated, which is available under the PCLCrypto.NetFxCrypto class.

Create a buffer filled with cryptographically strong random data

// WinRT-like API
uint length = 15;
byte[] cryptoRandomBuffer = WinRTCrypto.CryptographicBuffer.GenerateRandom(length);

// .NET Framework-like API
byte[] cryptoRandomBuffer = new byte[15];
NetFxCrypto.RandomNumberGenerator.GetBytes(cryptoRandomBuffer);

Generate a random number

uint random = WinRTCrypto.CryptographicBuffer.GenerateRandomNumber();
uint randomFrom0To15 = WinRTCrypto.CryptographicBuffer.GenerateRandomNumber() % 16;
