嗨我正在開發一個Air App，需要使用HMACSHA512加密標準通過http api進行身份驗證和簽名。AS3 Air App與HMACSHA512加密
我發現了一個AS3庫，它看起來貨物https://github.com/rubo/flame但其已爲柔性準備，我已經有很多試圖讓它在空氣/ Flash IDE中工作和/或提取的核心功能麻煩我需要。
這將是美妙的，如果有人可以幫助我獲得通過Flash IDE裝載workine簡單的例子代碼加密郵件「你好」像火焰庫/ SWC ...
import flame.crypto.HMACSHA512;
var test:HMACSHA512 = new HMACSHA512(ByteArrayUtil.fromHexString('mySecretKey'));
trace('encrypted output = ' + test.encryptString('hello'));
謝謝提前！
由於基於ECMAScript的actionscript和javascript，您可以始終（並且幾乎總是很容易）從javascript中移植一些東西。 例如執行加密算法。
但是！有人已經這樣做了。 SEE HOW
優化和改進的代碼。我從它全部拆除並不適用於HMACSHA512
