JavascriptでのSHA-512実装をActionscriptに移植するのを誰かが手伝ってくれるかどうか疑問に思っています。JavascriptとActionscriptは同じ起源を共有しているので、Actionscriptに慣れている人にとっては移植が簡単だと思います。
javascriptのsha512のコードはここにあります：

これが私が移植したコードです。コードはInt64.asとSha512.asの2つのファイルに分かれており、どちらもcom.cryptoパッケージに属しています。

上記（これがあるべき場所）にコメントを投稿することはできませんが、文字列にヌル文字を追加するときのActionscriptの想像上の動作のために、このコードを使用する一部の署名でエラーが発生します（そうではありません）。
私が使用している16進エンコードされたhmacをすばやく汚く修正するために、hex_hmac_sha512関数を（それが呼び出すエンコードのためだけに）変更し、binb2hex関数を次のように追加しました。
private function hex_hmac_sha512(key, data) {
key = str2rstr_utf8(key);
data = str2rstr_utf8(data);
var bkey = rstr2binb(key);

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);
return binb2hex(binb_sha512(opad.concat(hash), 1024 + 512));
}
private function binb2hex(input) {
var hex_tab = hexcase ? "0123456789ABCDEF" : "0123456789abcdef";
var output = "";
