deb包 deepin-deb-verify -f ./com.kinggrid.surread_3.0.0.134_amd64.deb #加上-d参数还可以dump出签名的证书 deepin-deb-verify -f ./com.kinggrid.surread_3.0.0.134_amd64.debdeepin-dep-verify这个程序属于deepin-elf-sign-tool这个包，这个包提供的工具主要用于对deb包和elf格式二进制签名或者校验签名 然后再查看已签名二进制elf文件情况。 readelf -S ./SurRead There are 32 section headers,
