(Chilkat2-Python) Generate an RSA Key and Get as Base64 DERDemonstrates how to generate a 2048-bit RSA key and return the public and private parts as unencrypted Base64 encoded DER. Note: This example requires Chilkat v11.0.0 or greater.
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() # Generate a 2048-bit key. privKey = chilkat2.PrivateKey() success = rsa.GenKey(2048,privKey) if (success == False): print(rsa.LastErrorText) sys.exit() # Get the public part of the key. pubKey = chilkat2.PublicKey() privKey.ToPublicKey(pubKey) # There are two possible formats for representing the RSA public key # in ASN.1 (DER). The possible formats are PKCS1 and PKCS8. # We can get either by setting bChoosePkcs1 to True or False. bChoosePkcs1 = True pubKeyBase64Der = pubKey.GetEncoded(bChoosePkcs1,"base64") print("Public Key Base64 DER:") print(pubKeyBase64Der) # Get the private key as Base64 DER: # We can get PKCS1 or PKCS8, but with different methods: privKeyPkcs1 = privKey.GetPkcs1ENC("base64") print("Private Key PKCS1 Base64 DER:") print(privKeyPkcs1) privKeyPkcs8 = privKey.GetPkcs8ENC("base64") print("Private Key PKCS8 Base64 DER:") print(privKeyPkcs8) |
