Iterate Keys and Certs in PEM

See more PEM Examples

Demonstrates how to access each of the private keys and certs contained within a PEM. Chilkat2-Python

import sys
import chilkat2

success = False

# This example assumes the Chilkat API to have been previously unlocked.
# See Global Unlock Sample for sample code.

pem = chilkat2.Pem()

# Load the PEM from a file.
# If the PEM is encrypted, provide a password.  Otherwise pass an empty string for the password.
password = "myPassword"
success = pem.LoadPemFile("../myPemFiles/myPem.pem",password)
if (success == False):
    print(pem.LastErrorText)
    sys.exit()

# Note: If the app already has the PEM pre-loaded in a string variable, then load it 
# by calling LoadPem instead.  
pemContent = "... the PEM contents ..."
success = pem.LoadPem(pemContent,password)
# Check for success as before..

# Iterate over the private keys.
numPrivateKeys = pem.NumPrivateKeys
i = 0

privKey = chilkat2.PrivateKey()
while i < numPrivateKeys :
    pem.PrivateKeyAt(i,privKey)
    print("Private Key " + str(i) + " is " + str(privKey.BitLength) + " in length")
    i = i + 1

# Iterate over the certificates.
cert = chilkat2.Cert()
numCerts = pem.NumCerts
i = 0
while i < numCerts :
    pem.CertAt(i,cert)
    print("Certificate " + str(i) + " : " + cert.SubjectDN)
    i = i + 1
