SmartContract.Essentials 1.0.2

Setting up DI

Encryption providers can be created through a factory, allowing you to adhere to SOLID guidelines and test your implementation more easily. Begin by adding the factory to your container.

services.AddSingleton<ICipherFactory, AesCipherFactory>();

Encrypting personal data

var customerName = "Benjamin Swift";

CbcResult customerNameEncryptionResult;
try
{
    using var cbc = _cipherFactory.CreateCbcProvider();
    customerNameEncryptionResult = cbc.Encrypt(customerName);
}
catch (CryptographicException e)
{
}
catch (ArgumentException e)
{
}

// persist cipher to contract
// give user control of key and IV

Decrypting personal data

string customerName;
try
{
    using var cbc = _cipherFactory.CreateCbcProvider();
    customerName = cbc.Decrypt(customerNameCipher, key, iv);
}
catch (CryptographicException e)
{
}
catch (ArgumentException e)
{
}

Generating a random string

var generator = new UrlFriendlyStringGenerator();
var value = generator.CreateUniqueString(24);
