How to retrieve certificates from a pfx file with c#? -

i've been googling around half day looking way read .pfx file , import certificates certstore.

so far, able read .pfx file x509certifcate , able import 1 certificate within .pfx file. far good, there 3 certificates in .pfx file , when loading .pfx x509certificate, not able see other 2 certificates.

the certificate exported

*personal information exchange - pkcs #12 (.pfx)

• include certificates in certification path if possible

• enable strong protection (requires ie 5.0, nt 4.0 sp4 or above)

those options selected when exporting certificate(s). know there 3 certificates because manually go certstore (mmc) , import personal folder myself.

you should able collection object containing certs in .pfx file using x509certificate2collection class... here's c# example code:

string certpath = <your pfx file path>; string certpass = <your password>;  // create collection object , populate using pfx file x509certificate2collection collection = new x509certificate2collection(); collection.import(certpath, certpass, x509keystorageflags.persistkeyset); 

then can iterate on collection:

foreach (x509certificate2 cert in collection) {     console.writeline("subject is: '{0}'", cert.subject);     console.writeline("issuer is:  '{0}'", cert.issuer);      // import certificates x509store objects } 

depending on type of certificate (client cert, intermediate ca cert, root ca) you'll need open proper cert store (as x509store object) import it.

check out x509store docs:

http://msdn.microsoft.com/en-us/library/system.security.cryptography.x509certificates.x509store.aspx

and different members in storename enumeration:

http://msdn.microsoft.com/en-us/library/system.security.cryptography.x509certificates.storename.aspx

from understand, want use storename.my client certificates contain private key, storename.certificateauthority intermediate ca certs, , storename.root root ca certs.
