Weak Key for DES in .NET


Weak Key for DES in .NET

wish helps you It's pretty simple. You are calling same method CreateWeakEncryptor in CreateDecryptor method. So, finally MethodInfo mi = cryptoProvider.GetType().GetMethod("_NewEncryptor", BindingFlags.NonPublic | BindingFlags.Instance);
always return a encryptor method. To that method while invoking you are passing 0 as the last parameter which is always equals to the enum CryptoAPITransformMode.Encrypt.

How portable is weak linking? #pragma weak my_symbol

How portable is weak linking? #pragma weak my_symbol

Does that help #pragma is, by definition, not portable.
And weak linking is done at link time (surprisingly enough). It allows a function (or any symbol, really) with the same signature to override another. That means a strong one will be chosen in preference to the weak one but, if there's no strong one, the weak one will be used.

I wish did fix the issue. In your second code example you have a temporary retain cycle. When the completionHandler block has been called, the block is released and with it the captured self, so that the release cycle is broken.
Objective-C: Should we use weak self within block or assign weak self to strong before using it?

Hope that helps Due to the volatile nature of weak variables, you should use them with care. If you are using weak variables in a multithreading environment, it is considered good practice to assign the weak variable to a strong one and check for nil before using. This will ensure that the object will not be released in the middle of your method, causing unexpected results.
Consider the following case:
code :
__weak id var;

//...

if(var != nil)
{
    //var was released here on another thread and there are not more retaining references.
    [anotherObj performActionWithAnObjThatMustNotBeNil:var]; //<- You may crash here.
}
Whether should computed properties be specified with 'weak' when referencing a weak-ref variable?

fixed the issue. Will look into that further You only need to use weak when you have circular references. I understand you have a (parent) TreeNode that has TreeNode children. The parent has a strong reference to each of the children, and therefore any reference from the child back to the parent must be weak or neither will destroy. You have done this by marking parentNode as weak.
In the case of rootNode, you only need to worry about what it returns. Since it returns _rootNodeCache, which is weak, you will not have a circular reference. You can prove this with the code below. Adding or removing weak from rootNode makes no difference. However, removing weak from _rootNodeCache or parentNode results in circular references and deinit not being called.
code :
class TreeNode {
    var name: String = ""
    var childNodes = [TreeNode]()
    weak var parentNode: TreeNode?
    private weak var _rootNodeCache: TreeNode?
    var rootNode: TreeNode? {
        return _rootNodeCache
    }
    init(_ name: String, _ root: TreeNode?, _ parent: TreeNode?) {
        self.name = name
        _rootNodeCache = root
        parentNode = parent
        if let parent = parent {
            print("Adding \(name) to \(parent.name)")
            parent.childNodes.append(self)
        }
    }
    deinit {
        print("deinit \(name) \(childNodes.count) children")
    }
    func show() {
        print("\(name) has \(childNodes.count) children")
        for child in childNodes {
            child.show()
        }
    }
}

func addChildren(root: TreeNode) {
    let child = TreeNode("child", root, root)
    TreeNode("grandchild", root, child)
}

var root: TreeNode? = TreeNode("root", nil, nil)
addChildren(root!)
root!.show()
root = nil
Flow no-weak-types warning: optional argument of weak type with default value

Flow no-weak-types warning: optional argument of weak type with default value

wish help you to fix your issue The warning you are seeing is from ESLint, specifically the eslint-plugin-flowtype plugin, and not from Flow itself.
However, it's warning you about something valid. Object is an unsafe type in Flow. It is equivalent to any (it used to have some subtle differences, but no longer does). In general it is probably worthwhile to spell out the properties explicitly, even if they are complicated, with something like this:
code :
type Init = {
  someProp: string,
  someOtherProp: number;
}

export default (resource: string, init?: Init = {}) => {}
