PKCS11 Sessions

See more PKCS11 Examples

Sample code showing how to open a PKCS11 session and then later close it.

Note: This example requires Chilkat v9.5.0.88 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.

let pkcs11 = chilkat::Pkcs11::new();

// Set your shared lib path -- either a full path to the DLL, .so, or .dylib,
// or just the filename if the driver is in a location that can be automatically found. (Such as in C:\Windows\System32)
pkcs11.set_shared_lib_path("ShuttleCsp11_3003.dll");

// Starting in Chilkat v9.5.0.96, there is a shorter way to establish
// a PKCS11 session with login.
// The QuickSession method was added in v9.5.0.96 and is the equivalent of 
// calling Initialize, OpenSession, and Login.  

if pkcs11.initialize().is_err() {
    println!("{}", pkcs11.last_error_text());
    return;
}

// Pass -1 for the slotID to open a session on the first non-empty slot.
let slot_id = -1;

// Open a read/write session.
let read_write = true;
if pkcs11.open_session(slot_id, read_write).is_err() {
    println!("{}", pkcs11.last_error_text());
    return;
}

// Do whatever is needed...
// ...
// ...

// When finished, close the session.
// It is important to close the session (memory leaks will occur if the session is not properly closed).

if pkcs11.close_session().is_err() {
    println!("{}", pkcs11.last_error_text());
    return;
}

println!("PKCS11 session successfully opened and closed.");
