问题 In a TLS handshake configured with a client authentication, there is a step where the server receives the client's certificate and choose to trust it or not (for instance, in Java it is done via a TrustManager). I would like to know if the eventual "trust failure" message from the server is sent before or after the server made sure that the client really own that public key (for example, by receiving first some messages from the handshake encoded with the client's private key). The purpose of

问题 I need some suggestions on how to secure REST APIs and web based internal system using a single authentication system. I am looking into the possibility of using: oAuth 2.0 JA-SIG CAS Custom Implementation (implement two separate APIs) To secure REST APIs and redirect calls to specific API instance To authenticate web application users. 回答1: I assume you have a UI for your webapp and want to share your identity between your webapp and your web service. You can achieve that by : "cassifying"

问题 I am creating a bookmarklet that is to be used across a wide range of domains. I wanted to set some cookies to store temporary settings for this bookmarklet, so I assumed that setting a cookie from this script would assign the cookie to the domain of the script's origin. This was not the case, the bookmarklet is able to assign cookies to the domain of the current site being viewed. This is not suitable for my needs (this would remember settings per domain, rather than for the bookmarklet

问题 I'd like to sandbox a native code and use hooking of WinAPI and system functions to block or allow this program to perform some operations like reading/writing files, modify Windows registry, using an Internet connection. Is it a good and secure way to do so? How difficult would it be for that program to bypass such a security layer? 回答1: +1 to Hans, however if you are really into it then I can recommend Easyhook. I have personally used it successfully in Win XP, Vista and 7. I don't know how

问题 After getting negative comments on this answer - can i implement counter in the .text area without using registers?, I performed a little investigation, trying to understand if RWX memory pages are really non-usual and rare thing, or every popular program has some. (Science!) I attached to MSVS by WinDBG, executed !address /f:Image,PAGE_EXECUTE_READWRITE , and I saw a lot of lines like this: 7a534000 7a537000 3000 MEM_IMAGE MEM_COMMIT PAGE_EXECUTE_READWRITE Image "C:\WINDOWS\assembly

问题 Many of the encryption techniques I've seen can easily encrypt a simple 8 digit number like "12345678" but the result is often something like "8745b34097af8bc9de087e98deb8707aac8797d097f" (made up but you get the idea). Is there a way to encrypt this 8 digit number but have the resulting encrypted value be the same or at least only a slightly longer number? An ideal target would be to end up with a 10 digit number or less. Is this possible while still maintaining a fairly strong encryption?

问题 If I write the following code: static constraints = { password blank: false, password: true , validator:{ val, obj -> if (obj.password != obj.confirmarPassword) return 'usuario.password.dontmatch' } confirmarPassword bindable: true } } static transients = ['confirmarPassword'] The following error appears after introducing the same password in password and confirmarPassword : null id in usuario.Usuario entry (don't flush the Session after an exception occurs) I found out the root of the
