delphi中要计算SHA512用哪套代码或组件较好啊？

TurboPower LockBox 3 including the new SHA-512/224 & SHA-512/256 介绍：http://lockbox.seanbdurkin.id.au/tiki-index.php
官网下载：http://sourceforge.net/projects/tplockbox/files/

erhan厉害，什么都知道。
我也去下载看看。

很郁闷啊，安装了但还是使用不上，因为发现程序功能是要实现php中
hash_hmac('sha512', 'The quick brown fox jumped over the lazy dog.', 'secret');
这样的。也就是说还有个KEY参数不知怎么传进去：
说明
string hash_hmac ( string $algo , string $data , string $key [, bool $raw_output = false ] )

应该是The quick brown fox jumps over the lazy dog，“The quick brown fox jumped over the lazy dog”少了s。其实The quick brown fox jumps over a lazy dog更短一些。:)

你要的那东东是HMAC_SHA512，LockBox实现了SHA512，但没有HMAC，有空帮你找下，或者你看下HMAC的算法做一个？呵呵

顶一下js都有了，delphi的应该也有现成的吧

原来这样也是可以滴
procedure TForm1.Button1Click(Sender: TObject);
var
        ss: TStringList;
        script:OleVariant;
begin
        ss := TStringList.Create;
        ss.LoadFromFile('d:\sha512.js');
        script:=CreateOleObject('ScriptControl');    //uses ComObj
        script.Language:='JavaScript';
        script.AddCode(ss.Text);
        Memo1.Lines.Add('sha521');
        Memo1.Lines.Add(script.Eval('hex_sha512(''The quick brown fox jumps over the lazy dog.'')'));
        Memo1.Lines.Add('hmac_sha512');
        Memo1.Lines.Add(script.Eval('hex_hmac_sha512(''secret'',''The quick brown fox jumps over the lazy dog.'')'));
        script := null;
        ss.Destroy;
end;
木啥说的了，js不爽的话，直接改成delphi代码了，这个是体力活，自己干吧，呵呵

谢谢楼上两位，不是delphi的比较好找，js版的我之前就得到过一个，这个也一并复制下来供参考吧。
说实话，桌面程序要调用这种外部代码也要优先考虑C版的了。
BTW,昨天我还在想着php中libmhash.dll输出的那个函数该怎么调用。:(

晕死，结个帖几分钟都还不行，这CSDN无语了，以后再来看吧

经实践，这真是一个糟糕的主意。翻译不下去了，直接调用又受计算速度和线程安全两方面制约，不现实。好在后来用“delphi sha512 hmac”竟然一下就搜索到了这个开源的好用的库，经测试，完全OKhttp://blog.sina.com.cn/s/blog_79a2178d01010rv6.html
MD5, SHA-1, SHA256, SHA512, HMAC, RC4, DES, RSAin delphihttp://fundementals.sourceforge.net/dl.html
http://sourceforge.net/projects/fundementals/files/Fundamentals4/FundamentalsHash415.zip/download调用方式很简单：
SHA512DigestToHex(CalcHMAC_SHA512('secret', strSource));当然还是要感谢erhan，你那个代码以后我们在js项目中可用。

调试易

delphi中要计算SHA512用哪套代码或组件较好啊？
