无法使用 Windows 签名工具进行代码签名

Question

我试图通过创建我自己的自签名证书并成功签署文件来了解 Windows 上可执行文件的代码签名。 signtool 抛出错误并说“未找到符合所有给定条件的证书”。

我做错了什么？

这是我所做的：

按照 MS 和其他博客的一些说明，我创建了一个自签名证书，如下所示：

New-SelfSignedCertificate -certstorelocation Cert:\LocalMachine\my -dnsname cameronnokes.com

$pwd = ConvertTo-SecureString -String "password" -Force -AsPlainText

Export-PfxCertificate -cert Cert:\LocalMachine\my\C7A94086D80A42151551A9FCCEACBC0B4A9ABA1A -FilePath 'C:\Users\Cameron Nokes\selfcert.pfx' -Password $pwd

Get-ChildItem -Recurse Cert:\LocalMachine\my

最后一个 Get-ChildItem 命令显示指纹和主题，看起来就像我期望的那样。

现在，我在 cmd 中运行：

signtool.exe sign /f selfcert.pfx /p password /debug test.ps1


The following certificates were considered:
    Issued to: cameronnokes.com
    Issued by: cameronnokes.com
    Expires:   Sat Aug 05 12:37:28 2017
    SHA1 hash: C7A94086D80A42151551A9FCCEACBC0B4A9ABA1A

After EKU filter, 0 certs were left.
After expiry filter, 0 certs were left.
After Private Key filter, 0 certs were left.
SignTool Error: No certificates were found that met all the given criteria.

Answer 1

花点时间记住 certreq 的怪癖，默认情况下它就在那里，您可以使用它为您生成密钥。

提出这个请求.inf：

[NewRequest]
Subject = "CN=cameronnokes.com"
Exportable = TRUE
KeyLength = 2048
KeySpec = 1
KeyUsage = 0xA0
RequestType = Cert

[EnhancedKeyUsageExtension]
OID = 1.3.6.1.5.5.7.3.3 ; Code signing

然后运行这个命令：

certreq -new request.inf nothing.csr

然后您可以同时删除 request.inf 和 nothing.csr。此时，您的个人商店中有一个自签名代码签名证书。

$Certificate = Get-ChildItem cert:\CurrentUser\My |
    Where-Object { $_.EnhancedKeyUsageList.FriendlyName -eq 'Code Signing' -and $_.NotAfter -gt (Get-Date) } |
    Sort-Object NotAfter |
    Select-Object -Last 1

你在选择证书的时候不会真的想这么模糊，这样只是为了示例。

最后，签个ps1：

Set-AuthenticodeSignature test.ps1 -Certificate $Certificate

简单吧？
