Rust Requires Chilkat v11.0.0+

PKCS11 Import an Existing RSA Public Key onto the HSM

See more PKCS11 Examples

Demonstrates how to import an existing RSA Public Key onto a smart card or token.

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

Rust

// This example requires the Chilkat API to have been previously unlocked.
// See Global Unlock Sample for sample code.

// Note: Chilkat's PKCS11 implementation runs on Windows, Linux, Mac OS X, and other supported operating systems.

// (The format of the path will change with the operating system.  Obviously, "C:/" is not used on non-Windows systems.
