我正在尝试为我的组织实施 OpenID Connect 规范。我在测试依赖方应用程序中使用 Microsoft 的 OpenID Connect OWIN 实现来验证我的协议实现。
我公开了以下元数据文档:
{
"issuer": "https://acs.contoso.com/",
"authorization_endpoint": "http://localhost:53615/oauth2/auth",
"token_endpoint": "http://localhost:53615/oauth2/token",
"userinfo_endpoint": "http://localhost:53615/connect/userinfo",
"jwks_uri": "http://localhost:53615/connect/keys",
"ui_locales_supported": [
"en-GB"
]
}
签名密钥作为本文档公开:
{
"keys": [
{
"n": "xpXxl3M-YkZlzQJdArO1TfOGT2no-UL4dbZ7WuSCNIsSfyGDaqUXjMMHNyq9yD3vp-NCyk8kmn7d5XqHufnceXJM8q4xTrhN3lvywdBSbR-dwXsA-B-MJVgfiK0d_z-mxP9ew2Hj9-KkWbWCzsswlWp3gZ4mB4RGutB1IRSzXVIbvZ-MtKUb6XUDU4LDb_c1xCEXWZxhR-o1a1dLfObH2hHJ-w5y6odGlKtOFx4i4h0u7-Oj5R6k5b2YXEHM0IuYeN0u0sQvrTecokntGzPrvhnKy69I7Z_az5rC5kgloh25D9lTbe4vcRU7FXlYCFYDZsT0_IkGIXRi7brOS4f1ow",
"e": "AQAB",
"kty": "RSA",
"use": "sig",
"alg": "RS256",
"kid": "F8A59280B3D13777CC7541B3218480984F421450"
}
]
}
身份令牌是使用JwtSecurityToken
类及其关联的处理程序生成的,使用X509SigningCredentials
类。此代码代表令牌是如何构造的,并作为响应数据的参数返回给调用系统。
var credentials = new X509SigningCredentials(cert); // My certificate.
var issuedTime = DateTime.UtcNow;
var expiresTime = issuedTime.AddMinutes(5);
var epoch = new DateTime(1970, 01, 01, 0, 0, 0);
var claims = new[]
{
new Claim("sub", Guid.NewGuid().ToString()),
new Claim("iat" Math.Floor((issuedTime - epoch).TotalSeconds).ToString()),
new Claim("nonce", nonce), // Value from client
}
var token = new JwtSecurityToken(
"https://acs.contoso.com",
client_id, // Value from client
claims,
new Lifetime(issuedTime, expiresTime),
credentials);
var handler = new JwtSecurityTokenHandler();
parameters.Add("id_token", handler.WriteToken(token)); // Outgoing parameters.
当我尝试将签名的令牌传递回依赖方应用程序时,OWIN 中间件接受 POST 并尝试验证令牌的签名。这样做会引发以下异常:
SecurityTokenSignatureKeyNotFoundException:IDX10500:签名验证失败。无法解析 SecurityKeyIdentifier: 'SecurityKeyIdentifier (IsReadOnly = False, Count = 1, Clause[0] = X509ThumbprintKeyIdentifierClause(Hash = 0xF8A59280B3D13777CC7541B3218480984F421450))', 令牌: '{"typ":"JWT","alg":"RS25 "x5t":"-KWSgLPRN3fMdUGzIYSAmE9CFFA"}.{"iss":" https://test.accesscontrol.net/","aud":"test","nbf":1404917162,"exp":1404917462,"sub":"60eb55ec-0699-4068-bfa6-41666fc2b2e9","iat":"1404917162"} RawData: eyJ0eXAiOiJKV1QiLCJhbGciOiJSUzI1NiIsIng1dCI6Ii1LV1NnTFBSTjNmTWRVR3pJWVNBbUU5Q0ZGQSJ9. eyJpc3MiOiJodHRwczovL2Fjcy5zdXJlY2xvdWQuY29tLyIsImF1ZCI6InRlc3QiLCJuYmYiOjE0MDQ5MTcxNjIsImV4cCI6MTQwNDkxNzQ2Miwic3ViIjoiNjBlYjU1ZWMtMDY5OS00MDY4LWJmYTYtNDE2NjZmYzJiMmU5IiwiaWF0IjoiMTQwNDkxNzE2MiJ9.xkP0RwlX3CYfU0KhFsVvLJC94WK22DTqNTm71cfjiJ8VUHv3b2YhDqfq70N8mQEyiR8vTR6OQqnO6UqXqX4RXUs6ZkfK9Liv3n9NhCs97wJhP2jfefJYeScYtRmWcNNWSSL7vkm2JXQfwKOQTnOGp-ba04TtI6jVrjhOQXH43eCJ9vNuBUzdD-t8CAdmnbvH0nWpIB8kWbw5v8Sa0aQuxMjJYbLC_2Iw3X13dqnyVjp4fA7eSB8N7c1it0KEB-VKfUqiGD3VecyEZGGZbaGE8rvVet5QrY1lJ3V4yM8j6-xDc5Yndc4swOun0L3D6TYk-8gdVXUJDRjbv1ZuhZltsw'.
该组件仍然是预发布的,所以这可能是实现中的一个缺陷,但是我想假设这是我的错误,直到所有可能性都被排除。
有什么我正在做的事情显然是错误的,还是我应该做些什么来准确理解为什么签名无法验证?
