[原创] C# .NetCore 跨平台RSA加密实现

注意，文中提到的代码由于时间原因，没有经过严格跨平台测试，只是编译通过，在本地windows平台下测试正常。其它平台大家自行测试，如有时间，本人后面测试完后再来更新此文。相信很多朋友.NetCore下使用RSA时，如下图所示，都是用的这个第三方NuGet包这个包用起来确实很方便，它可以很方便的生成密钥对供我们调用，也可以很方便的实现RSA加密和解密。网上搜索到的结果基本上都是它的。本以为我也可以这样风平浪静心安理得的一直使用，但是直到有一天，我把它引入了一 ...

安全地在前后端之间传输数据 - 「1」技术预研

引已经不是第一次写这个主题了，最近有朋友拿 5 年前的《Web 应用中保证密码传输安全》来问我：“为什么按你说的一步步做下来，后端解不出来呢？”加解密这种事情，差之毫厘谬以千里，我认为多半就是什么参数没整对，仔细查查改对了就行。代码拿来一看，傻眼了……没毛病啊，为啥解不出来呢？时间久远，原文附带的源代码已经下不下来了。翻阅各种参考链接的时候从 CodeProject 上找了个代码，把各参数换过去一试，没毛病呀！这可奇了怪了，于是去 RSA.js 的文档（没有专门的文档，就是文 ...
