在原有项目的基础上兼容了小程序生态,具体修改可以看git提交记录📝。
基于javascript
和TypedArray
的国密加密算法实现。
Implement of Chinese encrypt algorithm in JavaScript and TypedArray.
为了兼容浏览器环境和node.je环境,这里我们使用了TextEncoder和Base64.js。
Here we use TextEncoder and Base64.js for both browser and node.js environment.
由于使用了TextEncoder
,所以暂时不支持Edge
。Node.js版本最低为8,建议使用最新的LTS版本。
Because of using TextEncoder
, this code cannot run in Edge
browser. Node.js
‘s version should at least be 8, and the newest LTS version is recommended.
