# Starting in v9.5.0.49, all Chilkat classes can be unlocked at once at the beginning of a program
# by calling UnlockBundle.  It requires a Bundle unlock code.

# The Chilkat PEM class was introduced in v9.5.0.49.  
# It requires the bundle to be unlocked, as shown above.

# Load the .p7b from a file.

# Note: If the app already has the p7b loaded in memory, the LoadP7b method
# may be called instead.  (see the online reference documentation)

# Iterate over the certificates.

    # cert is a CkCert
    cert = pem.GetCert(i)
    print("Certificate " + str(i) + " : " + cert.SubjectDN)
