Example: Crypt2.ClearEncryptCerts method

Demonstrates how to call the ClearEncryptCerts method. CkPython

import chilkat

success = False

crypt = chilkat.CkCrypt2()

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

cert1 = chilkat.CkCert()
# ...
# Load the cert from a source such as a .pfx/.p12 file, smart card, USB token, Apple keychain, Windows certificate store, etc.
# ...
crypt.AddEncryptCert(cert1)

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

cert3 = chilkat.CkCert()
# ...
crypt.AddEncryptCert(cert3)

# Params for public-key encryption to create PKCS7 enveloped-data
crypt.put_CryptAlgorithm("pki")
crypt.put_Pkcs7CryptAlg("aes")
crypt.put_KeyLength(256)
crypt.put_OaepHash("sha256")
crypt.put_OaepPadding(True)

bd = chilkat.CkBinData()
# ...
success = crypt.EncryptBd(bd)

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

cert4 = chilkat.CkCert()
# ...
crypt.AddEncryptCert(cert4)

cert5 = chilkat.CkCert()
# ...
crypt.AddEncryptCert(cert5)

# ...
# ...

# Encrypt using cert4 and cert5.
success = crypt.EncryptBd(bd)
