Load PEM Public/Private Key into RSA Object

See more RSA Examples

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

import sys
import chilkat

success = False

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

rsa = chilkat.CkRsa()

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

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 = chilkat.CkPrivateKey()

# 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!")
