JWT SecurityTokenInvalidSignatureException using RS256 PII is hidden

我在使用Microsoft的System.IdentityModel.Tokens.Jwt库验证一个使用RS256签名的JWT令牌时遇到了问题。这个令牌在JWT.io上验证正常。错误如下:

Microsoft.IdentityModel.Tokens.SecurityTokenInvalidSignatureException

IDX10503: 签名验证失败。尝试的密钥:'[PII已隐藏]'。

捕获的异常:

'[PII已隐藏]'。

令牌:'[PII已隐藏]'。

这是示例代码(我使用了LinqPad,并使用了System.IdentityModel.Tokens.Jwt v5.2.2 NuGet包):

void Main()
{
    var cText =
        "-----BEGIN CERTIFICATE-----\n" +
        "MIIBljCCAUACCQCIDMpqK7WfWDANBgkqhkiG9w0BAQsFADBSMQswCQYDVQQGEwJV\n" + 
        "UzETMBEGA1UECAwKU29tZS1TdGF0ZTESMBAGA1UECgwJTHV4b3R0aWNhMRowGAYD\n" +
        "VQQLDBFMdXhvdHRpY2EgZXllY2FyZTAeFw0xODA1MjMxNTE1MjdaFw0yODA1MjAx\n" +
        "NTE1MjdaMFIxCzAJBgNVBAYTAlVTMRMwEQYDVQQIDApTb21lLVN0YXRlMRIwEAYD\n" +
        "VQQKDAlMdXhvdHRpY2ExGjAYBgNVBAsMEUx1eG90dGljYSBleWVjYXJlMFwwDQYJ\n" +
        "KoZIhvcNAQEBBQADSwAwSAJBAKuMYcirPj81WBtMituJJenF0CG/HYLcAUOtWKl1\n" +
        "HchC0dM8VRRBI/HV+nZcweXzpjhX8ySa9s7kJneP0cuJiU8CAwEAATANBgkqhkiG\n" +
        "9w0BAQsFAANBAKEM8wQwlqKgkfqnNFcbsZM0RUxS+eWR9LvycGuMN7aL9M6GOmfp\n" +
        "QmF4MH4uvkaiZenqCkhDkyi4Cy81tz453tQ=\n" +
        "-----END CERTIFICATE-----";
    var c = new X509Certificate2(Encoding.ASCII.GetBytes(cText));
    var p = new TokenValidationParameters();
    p.IssuerSigningKeyResolver = (s, securityToken, identifier, parameters)
        => new[] { new X509SecurityKey(c) };
    var h = new JwtSecurityTokenHandler();
    var token = @"eyJhbGciOiJSUzI1NiJ9.eyJzdWIiOiJuLmNoaWVmZm8iLCJleHAiOjE1MjcyMzg4ODEsImlzcyI6Imx1eCJ9.BAaYzLwokmdKqLi6zKjGIpDXd__dZxi5PUWWHS3PSLPDYAInzPbEK8o4WxunoGD7eA0qtQNaxNpzeOc3BHrd4w";
    h.ValidateToken(token, p, out SecurityToken _);
}

最后,我希望知道如何去除[PII已隐藏],以便我可以看到更多关于错误的详细信息。在app.config或machine.config文件中将enableLoggingKnownPii和logKnownPII设置为true似乎没有产生任何影响。
