移植SHA512 Javascript的FPGA实现为ActionScript [英] Porting SHA512 Javascript implemention to Actionscript

本文介绍了移植SHA512 Javascript的FPGA实现为ActionScript的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我想知道是否有人能帮助我的SHA-512 FPGA实现在Javascript为ActionScript移植。由于JavaScript和ActionScript中共享相同的起源,我想移植它会是容易的谁是用来为ActionScript人。

I am wondering if anyone can help me in porting a SHA-512 implemention in Javascript to Actionscript. Since both Javascript and Actionscript share the same origin, I think porting it will be easy for people who are used to Actionscript.

在$ C $下在javascript SHA512可以在这里找到:

The code for sha512 in javascript can be found here:

感谢你。

推荐答案

下面是code。通过我的移植。在code之间两个文件Int64.as和Sha512.as分开,他们都属于com.crypto包。

Here is the code ported by me. The code is separated between two files Int64.as and Sha512.as, both of them belong to the com.crypto package.
