# Tell the crypt object to use 3 certificates.
# Do this by calling AddEncryptCert for each certificate.

# ...
# Load the cert from a source such as a .pfx/.p12 file, smart card, USB token, Apple keychain, Windows certificate store, etc.
# ...

cert2 = chilkat.CkCert()
# ...
crypt.AddEncryptCert(cert2)

cert3 = chilkat.CkCert()

# Let's say we now want to encrypt something else with different certs..
# First clear the encryption certs.
