(Go) PKCS11 Sessions

Note: This example requires Chilkat v9.5.0.88 or later.

Chilkat Go Downloads Go Package for Windows, MacOS, Linux, Alpine Linux, Solaris

    // 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.

    pkcs11 := chilkat.NewPkcs11()

    // 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.SetSharedLibPath("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.

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

        pkcs11.DisposePkcs11()
        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).
