问题 I am having a chain of X509Certificates starting with user certificate and ending with trusted CA certificate. For the test, I am experimenting with Google certificates. I want to check the revocation status of every certificate in Certificate chain. I am using following code: public static boolean isCertChainValid(ArrayList<X509Certificate> certificateList) { try { CertificateFactory certificateFactory = CertificateFactory.getInstance("X.509"); CertPath certPath = certificateFactory

问题 I'm reading the documentation for Cloud Identity and Access Management Method: projects.serviceAccounts.signBlob. I've got it figured out except for the body, which is { "bytesToSign": string } The documentation says that this should be The bytes to sign. A base64-encoded string. Gosh, how helpful! Can anyone explain what bytesToSign is? What do I put there? The service account private key? 回答1: The Google Cloud Platform (GCP) IAM API method projects.serviceAccounts.signBlob allows you to

问题 What problems am I likely to face / what should I consider? I'm starting from a point of rate-limiting per user, maybe overall, possibly per domain. I guess I'll parse_url(), make sure I set reasonable timeouts, etc. Is there a big class of security hole I need to watch out for? 回答1: Is there a big class of security hole I need to watch out for? yes! idk if it's big, but for example: you probably don't want to accept file:// url's (for example, would you want to accept file:///etc/passwd ?

问题 This is a question with a rather small scope, but I'm running a lot of windows command prompt commands that involve using the admin password. I can either have part of the command be "/user:administrator /password:examplepassword", where examplepassword is in plaintext, or I can just have "/user:administrator", and it prompts me for the password, which I then enter masked ( * ** * ** * ). So, my question is simply this: is entering the password in the plaintext secure? (obviously besides the

问题 I asked this question about my Firebase implementation. Essentially, I was trying to structure my Firebase database so that I could have a collection of objects, with some users accessing a subset of these objects. In my example, I have tasks. Multiple users will use this database, and per Firebase's suggestion, all the tasks for all users are flattened as children of one parent node. Each user can access their own tasks, indicated by a creatorId in a task object. Perhaps in the future

问题 The application had problems with allowing to be loaded into iframe. I have read a lot about it (and clickjacking). As it is necessary to load a page into the iframe withing the same origin, I have come to the following solution: Add the following to the global.asax file HttpContext.Current.Response.AddHeader("x-frame-options", "SAMEORIGIN") However, I know that not all browsers support this header. So, I want to add some additional javascript sollution. As I am not expert in javascript, I

问题 I am using Spring Security with a login page and a remember-me filter. The remember-me filtering can happen on any page of the application. But I want the same behaviour both when the user is authenticated from login page and from the cookie: I want to set some user information in session I want to redirect the user to the home page (always-use-default-target="true") I have seen that the success-handler for the remember-me tag is supported by Spring Security since the 3.1.0 (https://jira
