ByteDev.Crypto

Provides simple cryptographic related classes for hashing/verifying and encrypting/decrypting data in .NET.

Installation

ByteDev.Crypto has been written as a .NET Standard 2.0 library, so you can consume it from a .NET Core or .NET Framework 4.6.1 (or greater) application.

ByteDev.Crypto is hosted as a package on nuget.org. To install from the Package Manager Console in Visual Studio run:

Usage

Hashing

Simple example of hasing some clear text ("Password123") and verifying a guess is equal.

var service = new HashService();

string hash = service.Hash("Password123");

bool isLoginSuccessful = service.Verify("passwordGuess", hash);

Encryption

Simple example of encrypting a secret with a key and then decrypting it.

var algo = new RijndaelAlgorithm();

var keyFactory = new EncryptionKeyIvFactory(algo);
var keyIv = keyFactory.Create("Password1", Encoding.UTF8.GetBytes("someSalt"));

var service = new EncryptionService(algo);

byte[] cipher = service.Encrypt("mySecret", keyIv);

string clearText = service.Decrypt(cipher, keyIv);	// clearText == "mySecret"

Random

Example of creating a random string of a specified length using only the characters specified.

const string validChars = "1234567890";
const int length = 5;

using (var r = new CryptoRandom(validChars))
{
    string randomString = r.CreateRandomString(length);
}
