hashing a passwords with salt code example

Example: hash with salt

// Hash with salt in C#
static string HashString(string text, string salt = "")
{
    if (String.IsNullOrEmpty(text))
    {
        return String.Empty;
    }
    
    // Uses SHA256 to create the hash
    using (var sha = new System.Security.Cryptography.SHA256Managed())
    {
        // Convert the string to a byte array first, to be processed
        byte[] textBytes = System.Text.Encoding.UTF8.GetBytes(text + salt);
        byte[] hashBytes = sha.ComputeHash(textBytes);
        
        // Convert back to a string, removing the '-' that BitConverter adds
        string hash = BitConverter
            .ToString(hashBytes)
            .Replace("-", String.Empty);

        return hash;
    }
}
