X509Certificate Constructor (String, String)
Initializes a new instance of the X509Certificate class using the name of a PKCS7 signed file and a password to access the certificate.
Assembly: mscorlib (in mscorlib.dll)
ASN.1 DER is the only certificate format supported by this class. Calling this constructor with the correct password decrypts the private key and saves it to a key container.
If you create an X509Certificate certificate by specifying a PKCS7 signed file store for fileName, the X509Certificate is created for the certificate that signed the store rather than for any of the certificates within the store.
