DotNetXtensions.Cryptography (nuget): Some cryptography and compression related helper extension methods and types.        Extension methods that make it easy to get SHA hashes as well as AES-256 encryption on strings and byte-arrays.        XZip which makes it easy to convert byte arrays and Streams to and from a ZipArchive (a zip file).        RandomStringGenerator and RandomNumbers types, a PasswordStrengthEvaluator, and a CryptoRandom type (which inherits Random), which allows semi-crytographically secure random generation, based on RNGCryptoServiceProvider, but which uses a caching system that greatly expediates performance.
