我正在使用VS 2017和.NET 4.6.2開發C#Web Api MVC項目,我想用我的證書籤署JSON Web令牌。C#不能使用證書籤名JWT
這是我的代碼:
using SolutionDOC_Common;
using SolutionDOC_Interface.Repository.Authentication;
using SolutionDOC_SDK.Model;
using System;
using System.Collections.Generic;
using System.Configuration;
using System.IdentityModel.Tokens.Jwt;
using System.Security.Authentication;
using System.Security.Claims;
using System.Security.Cryptography;
using System.Security.Cryptography.X509Certificates;
using mit = Microsoft.IdentityModel.Tokens;
public string Build(Credentials credentials)
{
string thumbprint = ConfigurationManager.AppSettings["CertificateThumbprint"];
string tokenIssuer = ConfigurationManager.AppSettings["TokenIssuer"];
string tokenAudience = ConfigurationManager.AppSettings["TokenAudience"];
List<Claim> claims = new List<Claim>
{
new Claim(ClaimTypes.Name, credentials.Username),
new Claim(ClaimTypes.Surname, credentials.Alias)
};
X509Certificate2 cert = CertificateUtility.GetCertificateByThumbprint(thumbprint);
RSACryptoServiceProvider publicAndPrivate = (RSACryptoServiceProvider)cert.PublicKey.Key;
JwtSecurityToken jwtToken = new JwtSecurityToken
(
issuer: tokenIssuer,
audience: tokenAudience,
claims: claims,
signingCredentials: new mit.SigningCredentials(new mit.RsaSecurityKey(publicAndPrivate), mit.SecurityAlgorithms.RsaSha256Signature),
expires: DateTime.Now.AddDays(30)
);
JwtSecurityTokenHandler tokenHandler = new JwtSecurityTokenHandler();
// This throws the InvalidOperationException!
string tokenString = tokenHandler.WriteToken(jwtToken);
return tokenString;
throw new AuthenticationException();
}
的tokenHandler.WriteToken(jwtToken)
線,拋出一個InvalidOperationException
說
「IDX10638:無法創建SignatureProvider, 'key.HasPrivateKey' 是假的,不能創建簽名。鍵:Microsoft.IdentityModel.Tokens.RsaSecurityKey。'
相應證書的權限設置爲IIS_IUSRS用戶,因此它也可以讀取私鑰。該證書實際上是一個使用IIS生成的自簽名證書,該證書具有私鑰。 拇指指紋設置正確,所以我得到正確的證書。 所以我正確地得到了X509Certificate2
對象。 X509Certificate2
對象的PrivateKey屬性已填充。
它爲什麼不起作用?
