(PowerBuilder) PKCS11 Generate a Session EC Key on the HSM

See more PKCS11 Examples

Generates an EC key on the smart card or token and returns the public and private key handles. The generated EC key exists only for the duration of the PKCS11 session.

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