Russianسؤال
أتساءل عما إذا كان يمكن لأي شخص مساعدتي في تنفذ انفجار SHA-512 في جافا سكريبت إلى ActionScript. نظرا لأن كل من JavaScript و Actionscript يشارك نفس الأصل، وأعتقد أن Porting سيكون من السهل بالنسبة للأشخاص الذين يستخدمون إلى Actionscript.
يمكن العثور على رمز Sha512 في جافا سكريبت هنا:
http://pajhome.org.uk/crypt/md5/sha512.html.
شكرا لك.
المحلول
هنا هو الرمز الذي يستقلني. يتم فصل الرمز بين ملفين INT64.AS و SHA512.AS، كلاهما ينتمي إلى حزمة com.crypto.

نصائح أخرى
أنا غير قادر على نشر تعليق على ما سبق (حيث يجب أن يكون هذا)، ولكن هناك خطأ في بعض التوقيعات باستخدام هذا الرمز بسبب السلوك الخياري الخاص ب ActionScript عند إلحاق الحرف الخالي إلى سلسلة (لا).
للحصول على إصلاح سريع وقذرة إلى HMAC المشفرة HMAC وهو ما أستخدمه، قمت بتغيير وظيفة HEX_HMAC_SHA512 (فقط لمكالمات تكنولوجيا المعلومات فقط) وإضافة وظيفة binb2hex كما يلي:
private function hex_hmac_sha512(key, data) {
key = str2rstr_utf8(key);
data = str2rstr_utf8(data);
var bkey = rstr2binb(key);
if(bkey.length > 32) bkey = binb_sha512(bkey, key.length * 8);
var ipad = new Array(32)
var opad = new Array(32);
for(var i = 0; i < 32; i++) {
ipad[i] = bkey[i] ^ 0x36363636;
opad[i] = bkey[i] ^ 0x5C5C5C5C;
}
var hash = binb_sha512(ipad.concat(rstr2binb(data)), 1024 + data.length * 8);
