hash

问题 There is no straight forward bCrypt ( http://codahale.com/how-to-safely-store-a-password/) implementation in Objective-C, and while there are C code that does accomplish this, it's specifically for x86 processors, relying on BSD libraries. I'm building an iOS app which shares the same password hashes as corresponding Online (.NET and HTML5+Javascript) applications. I'm not quite where I ought to be, where I can read the awfully simplistic Java code ( http://www.mindrot.org/projects/jBCrypt/)

问题 I am creating a custom CDI scope and am using the BeanManager to get an injection of my NavigationHandler custom class. But the beans it returns are quite strange. So I use the BeanManager that way : public class ScreenContext implements Context { private NavigationHandler getNavigationHandler() { final Set<Bean<?>> beans = m_beanManager.getBeans(NavigationHandler.class); final Bean<?> bean = m_beanManager.resolve(beans); NavigationHandler reference = (NavigationHandler) m_beanManager

问题 I've gone through Eric Vyncke's PHP dkim script and copied how he was doing hashes for DKIM headers set in emails $DKIM_bh = base64_encode(pack('H*', sha1($body))); Would be used as so: 'bh='.$DKIM_bh.';'//... However when I validate the email message it tells me that the hash doesn't match. $headers .= 'DKIM-Signature: v=1; a=rsa-sha1; c=relaxed/simple; q=dns/txt; bh=';//... $body = 'Test PHP+SMTP authenticated email,3.'; bh='.base64_encode(pack('H*', sha1($body))).';';//... I'm not sure

问题 What is the best way to get the "anything" part after the domain part, using Javascript: http://www.domain.com/anything http://www.domain.com/#anything http://www.domain.com/any/thing For http://www.domain.com/#anything I would have to use window.location.hash . But for http://www.domain.com/anything I would have to use window.location.pathname . I'm using: window.location.href.replace(window.location.origin, "").slice(1) Are there any caveats with this solution? Is there a better way? 回答1:

问题 EDIT: I meant Permutations, not combinations. Thanks. I realize this is a rather open ended question, and I'm not looking for code per say, but really some hints where to start. What I want to make is a program, that can generate every combination of characters for a given length, i.e the user inputs 4, and the program will generate every possible combination of ASCII characters for a length of 4. Not really sure where I would start, perhaps the use of a hash table? Of course loops will be

问题 Trying to create a classic tic tac toe OOP in Ruby but am having trouble with my game_results() method. I realize this is not really complete and needs some more functionality but for now im just trying to fill my board with the inputted objects from the user and outputting the filled board and winner. When I can see on my board that we have a winner I call for the game_results() method and it gives me the correct winner but whenever a tie game occurs, I receive a error. Anybody got any ideas

问题 I would like to recognize and group duplicates values in a dictionary. To do this I build a pseudo-hash (better read signature ) of my data set as follow: from pickle import dumps taxonomy = {} binder = defaultdict(list) for key, value in ds.items(): signature = dumps(value) taxonomy[signature] = value binder[signature].append(key) For a concrete use-case see this question. Unfortunately I realized that if the following statement is True : >>> ds['key1'] == ds['key2'] True This one is not

问题 I have an Array of Hashes in a Hash that looks like this: $var = { 'items' => [ { 'name' => 'name1', 'type' => 'type1', 'width' => 'width1', }, { 'name' => 'name2', 'type' => 'type2', 'width' => 'width2', }, { 'name' => 'name3', 'type' => 'type3', 'width' => 'width3', } ] }; I wrote the following code to get the values from a file. my @members = ("name" => $name, "type" => $type, "width" => $width); $rec->{$items} = [ @members ]; push @var, $rec; I am not sure how to retrieve the values from
