password - the password that needs to be hashed. This should be converted
into a char array before passing.
salt- salt value that should append to the password.
iterations- no. of iterations to be done. This value can be used to adjust the speed of the algorithm.
keyLength- This is the required output length of the hashed function.
This function returns a byte array that needs to be converted into a string using a suitable hex encoder.
需要注意的是,加密的结果是字节数组。在存储到数据库的时候,可以转换为十六进制的字符串或者Base64字符串
[Test] public void Pbkdf2Test() { string saltString = "8291f825-5772-4b3b-a28c-18887099f6d4"; var array = Encoding.UTF8.GetBytes(saltString); GetHexString(array, 16); GetHexString(array, 128); GetHexString(array,256); GetHexString(array,512); var rfc2898DeriveBytes = new Rfc2898DeriveBytes("123", array, 4000); var result2 = rfc2898DeriveBytes.GetBytes(40); Console.WriteLine($"加密结果数组长度{result2.Length}"); var string2 = Convert.ToBase64String(result2); Console.WriteLine(string2); Console.WriteLine(string2.Length); } public void GetHexString(byte[] array, int keyLength) { var rfc2898DeriveBytes = new Rfc2898DeriveBytes("123", array, 4000); var result = rfc2898DeriveBytes.GetBytes(keyLength); Console.WriteLine($"加密结果数组长度{result.Length}"); var hexString = ByteArrayToString(result); Console.WriteLine(hexString); Console.WriteLine("========Split========"); } public static string ByteArrayToString(byte[] ba) { var hex = new StringBuilder(ba.Length * 2); foreach (var b in ba) hex.AppendFormat("{0:x2}", b); return hex.ToString(); }
