PKCS11 Generate Secret Key (such as AES)

See more PKCS11 Examples

Generates a symmetric secret key such as AES on the HSM.

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

;  Let's generate a 256-bit AES key on the token, which will exist for the duration of this session.
;  Symmetric keys, such as AES keys, are typically created (or imported) and used during a single session.

;  In virtually all cases, you'll want to create an AES key.
