wan24-Crypto-NaCl 2.1.0

wan24-Crypto-NaCl

This library adopts NSec to wan24-Crypto and extends the wan24-Crypto library with these algorithms:

How to get it

This library is available as NuGet package.

Usage

In case you don't use the wan24-Core bootstrapper logic, you need to initialize the NaCl extension first, before you can use it:

wan24.Crypto.NaCl.Bootstrapper.Boot();

This will register the algorithms to the wan24-Crypto library.

To set NaCl defaults as wan24-Crypto defaults:

NaClHelper.SetDefaults();

Per default the current wan24-Crypto default will be set as counter algorithms to HybridAlgorithmHelper.

Argon2id

A simple KDF operation example:

(byte[] stretchedPwd, byte[] salt) = KdfArgon2IdAlgorithm.Instance.Stretch(pwd, len: 32);

To use Argon2id as default KDF algorithm:

KdfHelper.DefaultAlgorithm = KdfArgon2IdAlgorithm.Instance;

You may specify Argon2id specific options using the KdfArgon2IdOptions, which cast implicit to/from a JSON string. The default options are the OWASP recommendations (46M memory usage):

(byte[] stretchedPwd, byte[] salt) = pwd.Stretch(len: 32, options: new KdfArgon2IdOptions()
	{
		// Configure the options here
	});// KdfArgon2IdOptions cast implicit to CryptoOptions

Or when using CryptoOptions:

CryptoOptions options = new()
{
	KdfAlgorithm = KdfArgon2IdAlgorithm.ALGORITHM_NAME,
	KdfIterations = KdfArgon2IdAlgorithm.Instance.DefaultIterations,
	KdfOptions = new KdfArgon2IdOptions()
	{
		// Configure the options here
	}
};
