javascript实现sha512和sha384算法(支持微信小程序),可分多次计算

news/2024/11/15 23:02:08/

概述:

`
本人前端需要实现sha512和sha384计算的功能,最好是能做到分多次计算。
本文所写的代码在现有sha512和sha384的C++代码,反复测试对比计算过程参数,成功改造成sha512和sha384的javascript代码,并成功验证好分多次计算sha512和sha384数据
因sha512和sha384,大部分计算过程一样,所以代码放在一起,一并测试。

测试平台:

已经在如下环境中测试通过,其他平台(浏览器)应该也不会有问题:
1、nodejs中node.exe运行
本js脚本按照版本ES5编写代码,当然微信小程序也能用。

技术难点:

在源代码c++中,本算法用到了大量的unsigned long long类型,而javascript版本ES5整型最大范围比c/c++语言中unsigned long long小,ES2000可以做到但是现在支持的不多,特别是微信小程序不支持。
故本次难点在于unsigned long long数据类型转换,本人特地写了基于javascript版本ES5的unsigned long long操作,实现载入、加减乘除,比较、移位运算,满足了本次需要。

功能代码:
