I get an "ASN1 bad tag value met" exception when trying to read a file containing the following PKCS7 message. I can open the file in windows fine. It is basically a chain of certificates.
Anybody know why this happens.
Thanks,
-Jalil
Here is my code:
SignedCms cms = new SignedCms();
TextReader tr = new StreamReader("./certs.p7b");
string certs = tr.ReadToEnd();
tr.Close();
System.Text.ASCIIEncoding encoding=new System.Text.ASCIIEncoding();
byte[] b = encoding.GetBytes (certs);
cms.Decode(b);
Here is the content of the file:
