我是一个新手和初学者,因为我的英语不好,所以我会讲长话,请帮助我。
公钥是Base64解码和SHA256。
使用C#和Python(Python结果正确。)
为什么会得到不同的结果?
如果愿意,我希望通过 C#代码得到答案(我的英语很差。)
非常感谢。

Base64解码==> SHA256
Python :
pubkey_der = base64.b64decode(pubKey)
sha = hashlib.sha256(pubkey_der).hexdigest()
for i in sha:
print(i),
print('\n'),
结果:890e947269d4e6d9c73883157f65aa6f12e20ad0a05ff518b5f9cb43cea28b89
C#:
private void button_go2_Click(object sender, EventArgs e)
{
string b64 = DecodeBase64(pubKey);
string result = GetSHA256HashFromString(b64);
}
private static string DecodeBase64(string pubKey)
{
string decode = string.Empty;
byte[] bytes = Convert.FromBase64String(pubKey);
decode = Encoding.UTF8.GetString(bytes);
return decode;
}
public string GetSHA256HashFromString(string strData)
{
byte[] bytValue = System.Text.Encoding.UTF8.GetBytes(strData);
try
{
SHA256 sha256 = new SHA256CryptoServiceProvider();
byte[] retVal = sha256.ComputeHash(bytValue);
StringBuilder sb = new StringBuilder();
for (int i = 0; i < retVal.Length; i++)
{
sb.Append(retVal[i].ToString("x2"));
}
return sb.ToString();
}
catch (Exception ex)
{
throw new Exception("GetSHA256HashFromString() fail,error:" + ex.Message);
}
}
