CkPython Requires Chilkat v11.0.0+

Generate RSA Public/Private Key Pair and Export to PEM

See more RSA Examples

_LANGUAGE_ example code showing how to generate an RSA public/private key pair and export to PEM files. 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()

#  Generate a 2048-bit key.  Chilkat RSA supports
#  key sizes ranging from 512 bits to 8192 bits.
privKey = chilkat.CkPrivateKey()
success = rsa.GenKey(2048,privKey)
if (success == False):
    print(rsa.lastErrorText())
    sys.exit()

pubKey = chilkat.CkPublicKey()
privKey.ToPublicKey(pubKey)

#  Save the private key in PEM format:
success = privKey.SavePemFile("privateKey.pem")
if (success == False):
    print(privKey.lastErrorText())
    sys.exit()

#  Save the public key in PEM format:
success = pubKey.SavePemFile(False,"publicKey.pem")
if (success == False):
    print(pubKey.lastErrorText())
