tar 原生不支持加密，可以自行安装 7-zip -pYourPasswd 加密文件夹

brew install p7zip
7z a  ~/Desktop/WeChat_history$(date +%F_%R).7z ~/Library/Containers/com.tencent.xinWeChat/Data/Library/Application\ Support/com.tencent.xinWeChat -pYourPasswd

命令解释

7z        : name and path of 7-Zip executable
a         : add to archive
secure.7z : name of destination archive
*         : add all files from current directory to destination archive
-pSECRET  : specify the password "SECRET"
