(Chilkat2-Python) Load PEM Public/Private Key into RSA Object

Demonstrates how to load a PEM key into the Chilkat RSA object.

Note: This example requires Chilkat v11.0.0 or greater.

Chilkat2 Python Downloads install with pip pip3 install chilkat2 or download... Python Module for Windows, Linux, Alpine Linux, MacOS

import sys
import chilkat2

success = False

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

rsa = chilkat2.Rsa()

# First demonstrate importing a PEM public key:
publicKeyPem = "PEM public-key data goes here"
pubkey = chilkat2.PublicKey()

success = pubkey.LoadFromString(publicKeyPem)
if (success == False):
    print(pubkey.LastErrorText)
    sys.exit()

success = rsa.UsePublicKey(pubkey)
if (success == False):
    print(rsa.LastErrorText)
    sys.exit()

# Demonstrate importing a PEM private key:
privateKeyPem = "PEM private-key data goes here"
privkey = chilkat2.PrivateKey()

# If the private key PEM is protected with a password, then 
# call LoadEncryptedPem.  Otherwise call LoadPem.
success = privkey.LoadPem(privateKeyPem)
if (success == False):
    print(privkey.LastErrorText)
    sys.exit()

success = rsa.UsePrivateKey(privkey)
if (success == False):
    print(rsa.LastErrorText)
    sys.exit()

print("OK!")
