Chilkat2-Python example code showing how to generate an RSA public/private key pair and export to PEM files.

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

import sys

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

rsa = chilkat2.Rsa()

# Generate a 1024-bit key.  Chilkat RSA supports
# key sizes ranging from 512 bits to 4096 bits.
success = rsa.GenerateKey(1024)
if (success != True):
    print(rsa.LastErrorText)
    sys.exit()

# Keys are exported in XML format:
publicKeyXml = rsa.ExportPublicKey()
print(publicKeyXml)

privateKeyXml = rsa.ExportPrivateKey()
print(privateKeyXml)

# Save the private key in PEM format:
privKey = chilkat2.PrivateKey()
success = privKey.LoadXml(privateKeyXml)
success = privKey.SavePemFile("privateKey.pem")

# Save the public key in PEM format:
pubKey = chilkat2.PublicKey()
success = pubKey.LoadFromString(publicKeyXml)
success = pubKey.SavePemFile(False,"publicKey.pem")
