# 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.
chilkatGlob = Chilkat::CkGlobal.new()
success = chilkatGlob.UnlockBundle("Anything for 30-day trial.")
if (success != true)
    print chilkatGlob.lastErrorText() + "\n";
    exit

# The Chilkat PEM class was introduced in v9.5.0.49.  
# It requires the bundle to be unlocked, as shown above.
pem = Chilkat::CkPem.new()

# Load the .p7b from a file.
success = pem.LoadP7bFile("../myCertFiles/myP7b.p7b")
if (success != true)
    print pem.lastErrorText() + "\n";
    exit
end

# 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.
numCerts = pem.get_NumCerts()
i = 0

while i < numCerts

    # cert is a CkCert
    cert = pem.GetCert(i)
    print "Certificate " + i.to_s() + " : " + cert.subjectDN() + "\n";

    i = i + 1
