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;
}
}
