uos如何判断软件包签名和二进制程序签名

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.deb 

deepin-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。

可以看到最后一个section是.sig

然后我们再dump 一下这个.sig节的内容呢

可以看到，这一节里面存的就是PKCS证书，不过我对这一套玩不熟。没法打印出证书信息来。BASE64解码就会报错。估计要怎么处理一下了。但对实际使用来说知道有这一节前面就足够了。不过也有某些安全厂商也会给他们发布的二进制文件进行签名。所以这里签名了未必就是UOS给签的，还有UOS私有化签名那一套用户自己签的或者是第三方安全厂商签的。
