how can generate key , iv each common string, may serve in encryption algorithm using aes in php? example: $key_string = derivate_in_valid_key("i love stackoverflow"); $iv_string = derivate__in_valid_iv("i love questions"); and in way can repeat derivation process in javascript also. you can use pbkdf2 derive key , iv password. cryptojs , php both provide implementations thereof. aes supports key sizes of 128, 192 , 256 bits, , block size of 128-bit. iv must same size block size modes such cbc. single invocation of pbkdf2 generate key the following code works generate iv. doing so, requires second random salt must sent alongside ciphertext. javascript ( demo ): var password = "test"; var iterations = 500; var keysize = 256; var salt = cryptojs.lib.wordarray.random(128/8); console.log(salt.tostring(cryptojs.enc.base64)); var output = cryptojs.pbkdf2(password, salt, { keysize: keysize/32, iterations: iterations });

i have wpf user control writing unit tests using nunit. 1 of tests displays control on window , clicks button on control. after looks confirm correct result received. using raisedevents looks , works correctly. mybutton.raiseevent(buttonargs); assert.areequal(expected, actual); i trying same thing using automation framework. like: buttonautomationpeer peer = new buttonautomationpeer(mybutton); iinvokeprovider invokeprov = (iinvokeprovider)(peer.getpattern(patterninterface.invoke)); invokeprov.invoke(); assert.areequal(expected, actual); now in case assert fails (as expected) because invoke called asynchronously , has not yet occurred @ time of assertion. i hoping resolve calling invoke on separate thread , waiting complete. thread thread = new thread(invokeprov.invoke); thread.start(); thread.join(); however still fails. sleeping: invokeprov.invoke(); thread.sleep(1000); showing dialog , forcing user continue, work. invokeprov.invoke(); system.windows.mess

i'm developing simple game player needs roll die , "the computer" needs it. i roll method performs differently each type of player. it's set bool parameter called isplayer (vs. iscomputer). players pass true value, computer false. there's if statements in method act accordingly. this seems clunky me. there better way? i thinking of creating playertype enum , each player have type still need pass type method. or change game variable type , method recognize that. any thoughts helpful. thanks. no seems fine , much-used , simple pattern. a bool fine time there 2 types of player (or behaviour) , moving enum if number of players extends beyond 2. alternatively there polymorphism roll method behaves differently depending on subclass implements it. require no parameters passed behaviour locked in class.
