PKCS11 Import an Existing AES Key onto the HSM

See more PKCS11 Examples

Demonstrates how to import an existing AES symmetric encrytion key onto the smartcard/token. The imported AES key is a session object, and only exists for the duration of the PKCS11 session. (AES keys are typically used for wrapping/unwrapping RSA and EC keys.)

Note: This example requires Chilkat v9.5.0.96 or later.
