如何使用cli从Linux下的Windows`exe`文件中提取签名数据

Question

如果您转到VirusTotal 链接，则会有一个名为文件信息的选项卡（我认为；我的是荷兰语）。你会看到一个标题为

"Authenticode signature block and FileVersionInfo properties"

我想使用 Linux cli 提取标题下的数据。例子：

Signature verification Signed file, verified signature
Signing date 7:43 AM 11/4/2014
Signers
[+] Microsoft Windows
[+] Microsoft Windows Production PCA 2011
[+] Microsoft Root Certificate Authority 2010
Counter signers
[+] Microsoft Time-Stamp Service
[+] Microsoft Time-Stamp PCA 2010
[+] Microsoft Root Certificate Authority 2010

我Camera.exe在 Windows 10 中使用了，以某种方式提取数据。

我解压了.exe文件，发现里面有一个CERTIFICATE文件，里面有很多不可读的数据，还有一些文字，我能读懂，也就是——大致——和上面的输出一样。

如何.exe使用 cli从Linux 下的 Windows文件中提取签名

Answer 1

在 Linux 上有一个工具osslsigncode可以处理 Windows Authenticode 签名。验证二进制签名会产生类似于您在示例中显示的输出；在vcredist_x86.exe我必须手上我得到：

$ osslsigncode verify vcredist_x86.exe
Current PE checksum   : 004136A1
Calculated PE checksum: 004136A1

Message digest algorithm  : SHA1
Current message digest    : 0A9F10FB285BA0064B5537023F8BC9E06E173801
Calculated message digest : 0A9F10FB285BA0064B5537023F8BC9E06E173801

Succeeded

您还可以提取签名：

osslsigncode extract-signature vcredist_x86.exe vcredist_x86.sig
