References the namespace.

using Nefe.Encryptor;

AES Algorithm

using (var aes = new AesEncryptor(RandomNumberGenerator.GetBytes(16)))
{
    // Encrypt it
    var cipherText = aes.Encrypt(Encoding.UTF8.GetBytes("Hello, AES."));
    Console.WriteLine(Convert.ToBase64String(cipherText));
    // Decrypt it
    Console.WriteLine(Encoding.UTF8.GetString(aes.Decrypt(cipherText)));
}

RSA Algorithm

using (var rsaEncryptor = new RsaEncryptor())
{
    // Encrypt
    var cipherText = rsaEncryptor.Encrypt(Encoding.UTF8.GetBytes("Hello, RSA."));
    Console.WriteLine(Convert.ToBase64String(cipherText));
    
    // Decrypt and Verify
    using(var rsaDecryptor = new RsaEncryptor(rsaEncryptor.XmlKey))
    {
        Console.WriteLine(Encoding.UTF8.GetString(rsaDecryptor.Decrypt(cipherText)));

        Console.WriteLine($"Data Verified: {rsaEncryptor.VerifyData(Encoding.UTF8.GetBytes("nefe"), rsaDecryptor.Sign(Encoding.UTF8.GetBytes("rsa")))}");
        
        Console.WriteLine($"Hash Verfied: {rsaEncryptor.VerifyHash(SHA256.Create().ComputeHash(Encoding.UTF8.GetBytes("rsa")), rsaDecryptor.Sign(Encoding.UTF8.GetBytes("rsa")))}");
    }
