在Windows窗体中使用SHA-256哈希文本

Question

String inputPass = textBox2.Text;
byte[] inputBytes = System.Text.Encoding.UTF8.GetBytes(inputPass);
byte[] inputHashedBytes = Sha256.ComputeHash(inputBytes);
String inputHash = Convert.ToBase64String(inputHashedBytes);

我得到一些奇怪的输出:

Q9nXCEhAn7RkIOVgBbBeOd5LiH7FWFtDFJ22TMLSoH8 =

通过输出哈希看起来像这样:

Answer 1

Encoding.UTF8.GetString 将字节解析为UTF8代码点.

SHA256散列是任意256位数,并不对应任何Unicode文本.

您可能希望通过调用以十六进制显示二进制值BitConverter.ToString().
你也可以打电话Convert.ToBase64String().

Answer 2

// this is where you get the actual binary hash
byte[] inputHashedBytes = Sha256.ComputeHash(inputBytes);

// but you want it in a string format, similar to a variety of UNIX tools
string result = BitConverter.ToString(inputHashedBytes)
   // this will remove all the dashes in between each two characters
   .Replace("-", string.Empty)
   // and make it lowercase
   .ToLower();
