如何使用Windows sdk和VC ++读取.cer文件？ [英] How can I read a .cer file with windows sdk and VC++?

问题描述

您好：

我有一个需要升级的VC ++ MFC应用程序。我的问题是：我必须加载".cer" 文件（不是来自商店的证书，而是文件本身）
并检索一些属性，例如序列号。 我知道使用.NET会更容易，但是我在VC ++中有完整的代码。我已经读过它可以使用
CAPICOM 完成：类似于Certificate.Load（" file.cer"）， 但我找不到标题。我试过了 
wincrypt.h 功能但不适合我的需求......你能给我一些建议吗？

I have a VC++ MFC application that needs to be upgraded. My problem is: I have to load a ".cer"  file (NOT the certificate from a store, but the file itself) and retrieve some attributes, like serial number.   I know it would be easier using .NET, but I have the full code in VC++ . I have read it could be done using CAPICOM : something like Certificate.Load("file.cer"),  but I can not find the headers. I have tried  wincrypt.h functions but none suits my needs... could you give me some suggestions?

非常感谢!!

推荐答案

您是否知道可以将.cer文件作为证书存储区进行访问？

Are you aware that a .cer file can be accessed as a certificate store?

考虑使用CertOpenStore（）如下：

Consider using CertOpenStore() as follows:

HCERTSTORE mycer = CertOpenStore (CERT_STORE_PROV_FILENAME, X509_ASN_ENCODING, NULL, (CERT_STORE_OPEN_EXISTING_FLAG | CERT_STORE_READONLY_FLAG), TEXT("myfile.cer") );
