#  LoadFromFile will load virtually any certificate format file.
#  It will auto-recognize the format and load appropiately.
#  A base64-encoded DER X.509 certificate file
#  contains the binary DER in base64 encoded form.
#  Therefore, it is a text file that will begin like this:
#  -----BEGIN CERTIFICATE-----
#  MIIFbjCCBFagAwIBAgIGdDPNv/L0MA0GCSqGSIb3DQEBBQUAMIHKMQswCQYDVQQG
#  EwJVUzEQMA4GA1UECBMHQXJpem9uYTETMBEGA1UEBxMKU2NvdHRzZGFsZTEaMBgG
#  ...

    print cert.lastErrorText()

#  DN = "Distinguished Name"
print "SubjectDN:" + cert.subjectDN()

print "Common Name:" + cert.subjectCN()
print "Issuer Common Name:" + cert.issuerCN()

print "Serial Number:" + cert.serialNumber()
