You can use sql mysql sqlite System.Security.Cryptography.MD5CryptoServiceProvider x = new System.Security.Cryptography.MD5CryptoServiceProvider(); byte [] bs = System.Text.Encoding.UTF8.GetBytes(password); bs = x.ComputeHash(bs); System.Text.StringBuilder s = new System.Text.StringBuilder(); foreach ( byte b in bs) { s.Append(b.ToString(x2).ToLower()); } password = s.ToString();
