问题 What would be the best way to go about giving users the ability to share a private link that enables anyone who clicks it to view a certain page/document/item that have privacy restrictions in place? In my case: A User creates events which are limited to certain groups of relationships in the database (namely: friends, friends of friends, etc.) I have a :before_filter in the event controller that checks the eligibility of the current logged in user to make sure that that user has permission

问题 I'm trying to do a function to hash passwords with this php function: http://be.php.net/manual/en/function.hash-pbkdf2.php. Here is the code: $hash_algo = "sha256"; $password = "password"; $salt = "salt"; $iterations = 1; $length = 1; $raw_output = false; $hash = hash_pbkdf2($hash_algo, $password, $salt, $iterations ,$length ,$raw_output); echo $hash; I got this error: Fatal error: Call to undefined function hash_pbkdf2().

问题 I have a process with permissions 4750. Two users exist in my Linux system. The root user and the appz user. The process inherits the permissions of a process manager that runs as "appz" user. I have two basic routines: void do_root (void) { int status; status = seteuid (euid); if (status < 0) { exit (status); } } /* undo root permissions */ void undo_root (void) { int status; status = seteuid (ruid); if (status < 0) { exit (status); } status = setuid(ruid); if (status < 0) { exit (status); }

问题 What are the application security risks of including a hidden 3rd Party iFrame? If I understand correctly... Click jacking isn't an issue for me because I own the parent page Same-Origin Policy prevents 3p frame from interacting my dom/cookies/js The frame is hidden, so I don't have to worry about anything that may be displayed in the frame However I did some experiments in the Chrome console and... 3p frame can call things like alert/prompt 3p frame can redirect the parent via location.href

问题 I'm using ASP.NET Membership and noticed there isn't a method in the Roles class to modify a role (its name for instance), only to create and delete them. Is it possible or it's not supported? EDIT: @CheGueVerra: Yes, nice workaround. Do you know (for extra credit :) ) why it's not possible? 回答1: There is no direct way to change a role name in the Membership provider. I would get the list of users that are in the role you want to rename, then remove them from the list, delete the role, create

问题 In JDK8 the class sun.security.x509.CertAndKeyGen does not exists anymore. Also sun.security.pkcs.PKCS10 is missing. In JDK7 they existed. What could be an alternatives to these classes methods? 回答1: I think you are looking for: sun.security.tools.keytool.CertAndKeyGen You'll find it inside the rt.jar under the JRE libraries. Keep in mind this class is outside of J2SE, it's likely only available with OpenJDK, so for example the GNU Compiler won't have it. 回答2: If you are using maven, put this
