问一下以前的数字签名证书(2000下，ＸＰ)，在vista 64BIT是否还可以继续使用？

  我公司原有代码签名证书,2001年申请的，现在想支持64 vista，不知道那个证书给驱动签名还是否有效？有知道的给解答一下，如果无效是否需要重新购买或对证书进行升级之类的？，谢谢！

对于应用层软件应该有效

对于驱动,有兄弟说只能用基于ms根证书发布的签名证书

只要没超期就应该是可以用的，我用的证书是V3的，签名的驱动可以在64位VISTA上用，不过需要用Vista DDK的签名工具。

用ms根证书和你自己的证书，两个一起用DDK带的工具作一个签名打到驱动上就可以了。

现在清楚了.需要用交叉签名,v3的证书和ms的根一起签才可以..

Determining which Cross-certificate to Use
Microsoft has issued one cross-certificate for each public key root certificate for CAs who have agreed to support the use of Software Publisher Certificates for kernel-mode code signing. This correct cross-certificate must be used when digitally signing kernel-mode code.

A CA might have one or more root certificates under which they issue Software Publisher Certificates.

To determine which cross-certificate you need to use for kernel-mode code signing:

1.
 In the Microsoft Management Console (MMC), add the Certificates snap-in (certmgr.msc) to view your code-signing certificate.
 
2.
 Locate your signing certificate in the certificate store, and then double-click it.
Your certificate is listed in one of these locations, depending on how the certificate was installed:

• The Current User, Personal, Certificates store, or
 
• The Local Machine Certificates store.
 
 
3.
 In the Certificate dialog box, select the Certification Path property tab, and then select the top-most certificate in the certification path.
This is the CA that is the issuing root authoring for your certificate.
 
4.
 To view the root authority certificate, select View Certificate, and then click the Details property tab.
 
5.
 Find the Issuer Name and Thumbprint for the issuing CA of this certificate, and then locate the corresponding cross-certificate in the "Root Authority Cross Certificate List" on this page.
 
6.
 Download the related cross-certificate from the "Root Authority Cross Certificate List," and use this cross-certificate when digitally signing kernel-mode code.
