如何阅读.pfx文件？ [英] How to read the .pfx file?

问题描述

我使用ASP.NET，C＃和iTextSharp的5.3.0用于创建和数字签名的PDF文件。然后，我需要使用PFX文件，而签约。有人能解释一下它会包含哪些内容？

I am using ASP.NET, C# and iTextSharp 5.3.0 for creating and digitally signing a PDF. Then I need to use pfx file while signing. Can someone explain what it will contain?

编辑：

谢谢，所以它具有密钥对。

Thanks, so it is having the keypair.

我也用这个code。

FileStream fs = new FileStream(CERT_PATH, FileMode.Open);
Pkcs12Store ks = new Pkcs12Store(fs, CERT_PASSW.ToCharArray());
string alias = null;
foreach (string al in ks.Aliases) 
{
if (ks.IsKeyEntry(al) && ks.GetKey(al).Key.IsPrivate) 
  {
    alias = al;
    break;
  }
}
  Certificate[] x = ks.getCertificateChain(alias)
  X509Certificate[] chain=new X509Certificate[x.length]
  for(int k=0;k<x.length;k++)
  {
      chain[k]=x[k].Certificate;
  }

谢谢，现在工作的罚款。

Thanks, It is working fine now.

推荐答案

请阅读iText的和数字签名白皮书：的 http://itextpdf.com/book/digitalsignatures

Please read the white paper on iText and digital signatures: http://itextpdf.com/book/digitalsignatures

一个PFX文件是包含私有和公共密钥对旧的类型的文件。你可以使用它，你会使用一个P12文件的方式。这是在文档中解释。注意＃2旧的答案不再适用。数字签名功能已经被完全重写。

A PFX file is an old type of file containing a private and public key pair. You can use it the same way you'd use a P12 file. This is explained in the documentation. Note that old answers on Stackoverflow no longer apply. The digital signature functionality has been completely rewritten.

如果你不知道如何在C＃中创建一个密钥库：

In case you don't know how to create a KeyStore in C#:

FileStream fs = new FileStream(CERT_PATH, FileMode.Open);
Pkcs12Store ks = new Pkcs12Store(fs, CERT_PASSW.ToCharArray());
string alias = null;
foreach (string al in ks.Aliases) {
    if (ks.IsKeyEntry(al) && ks.GetKey(al).Key.IsPrivate) {
        alias = al;
        break;
    }
}
