Create random numbers

This example code shows how to create a random number or buffer for use in cryptography in a WinUI app.

public string GenerateRandomData()
{
    // Define the length, in bytes, of the buffer.
    uint length = 32;

    // Generate random data and copy it to a buffer.
    IBuffer buffer = CryptographicBuffer.GenerateRandom(length);

    // Encode the buffer to a hexadecimal string (for display).
    string randomHex = CryptographicBuffer.EncodeToHexString(buffer);

    return randomHex;
}

public uint GenerateRandomNumber()
{
    // Generate a random number.
    uint random = CryptographicBuffer.GenerateRandomNumber();
    return random;
}
