一、简介
SM3密码杂凑算法是中国国家密码管理局2010年公布的中国商用密码杂凑算法标准。适用于商用密码应用中的数字签名和验证。 SM3是在[SHA-256]基础上改进实现的一种算法，其安全性和SHA-256相当。SM3和MD5的迭代过程类似，也采用Merkle-Damgard结构。…

Linux 字体管理相关
1基本上都用font-config这个包来。
几个常用命令保命先：
fc-list 查看系统上已安装的字体
fc-cache -fv 或者fc-cache -frv 用于生成字体cache或者重新生成字体cache
fc-cat -rv 查看fc cache内的内容 未完待续，字体这玩意儿也是一套体系。慢慢学…

警告：Extraneous non-props attributes (data) were passed to component but could not be automatica
这个警告一般是因为在Vue组件中，给组件传递了没有在组件props中声明的属性。这可能会导致意外行为，因为这些属性并不会被组件自动接收。
