I faced the same Issue, currently the work still in progress. when I finish the documentation, I might post it here. for time being: please check the draft: Enrich IdentityServer Documentation with OIDC and OAuth2 Flows section #73 Update: OIDC and OAuth2 Flows
As pointed out in the comments by @Kuba Šimonovský the accepted answer is missing other important factors: Actually, it is much much much more complicated. TL;DR One can infer that the refresh token lifespan will be equal to the smallest value among (SSO Session Idle, Client Session Idle, SSO Session Max, and Client Session Max). … Read more
Thanks to jwilleke, I have got a solution. To verify the RS256 signature of a JWT, it is needed to use the RSAPKCS1SignatureDeformatter class and its VerifySignature method. Here is the exact code for my sample data: string tokenStr = “eyJraWQiOiIxZTlnZGs3IiwiYWxnIjoiUlMyNTYifQ.ewogImlzcyI6ICJodHRwOi8vc2VydmVyLmV4YW1wbGUuY29tIiwKICJzdWIiOiAiMjQ4Mjg5NzYxMDAxIiwKICJhdWQiOiAiczZCaGRSa3F0MyIsCiAibm9uY2UiOiAibi0wUzZfV3pBMk1qIiwKICJleHAiOiAxMzExMjgxOTcwLAogImlhdCI6IDEzMTEyODA5NzAsCiAiY19oYXNoIjogIkxEa3RLZG9RYWszUGswY25YeENsdEEiCn0.XW6uhdrkBgcGx6zVIrCiROpWURs-4goO1sKA4m9jhJIImiGg5muPUcNegx6sSv43c5DSn37sxCRrDZZm4ZPBKKgtYASMcE20SDgvYJdJS0cyuFw7Ijp_7WnIjcrl6B5cmoM6ylCvsLMwkoQAxVublMwH10oAxjzD6NEFsu9nipkszWhsPePf_rM4eMpkmCbTzume-fzZIi5VjdWGGEmzTg32h3jiex-r5WTHbj-u5HL7u_KP3rmbdYNzlzd1xWRYTUs4E8nOTgzAUwvwXkIQhOh5TPcSMBYy6X3E7-_gr9Ue6n4ND7hTFhtjYs3cjNKIA08qm5cpVYFMFMG6PkhzLQ”; string[] tokenParts = tokenStr.Split(‘.’); RSACryptoServiceProvider rsa = new RSACryptoServiceProvider(); rsa.ImportParameters( new RSAParameters() { Modulus … Read more
I’m answering my own question as have discovered that some of the assumptions behind my question were wrong, so easier to clarify here, rather than re-write the question. An ID token is meant for proving to a Client that the user has authenticated, and who they are as a result. When a Client receives an … Read more
TL;DR IdentityServer = token encryption and validation services via OAuth 2.0/OpenId-Connect ASP.NET Identity = current Identity Management strategy in ASP.NET How can I authenticate similar to the way done in previous version’s of .Net does the old way still work or is there a newer version. I see no reason why you couldn’t achieve the … Read more
State and nonce seem to be similar. But if you dig deep, you will find that they serve different purposes. State is there to protect the end user from cross site request forgery(CSRF) attacks. It is introduced from OAuth 2.0 protocol RFC6749. Protocol states that, Once authorization has been obtained from the end-user, the authorization … Read more
Redirecting the user to the central authentication service when the user is not logged in to request credentials and issue a new authentication token is the common scenario in Single Sign On systems using well-known protocols like oauth2 or OpenId Connect However when this schema is used across domains the main drawback is that the … Read more
OpenID is about authentication (ie. proving who you are), OAuth is about authorisation (ie. to grant access to functionality/data/etc.. without having to deal with the original authentication). OAuth could be used in external partner sites to allow access to protected data without them having to re-authenticate a user. The blog post “OpenID versus OAuth from … Read more
