PKCS11 Find all Private Keys

See more PKCS11 Examples

Demonstrates how to list all private keys on an HSM.

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

Go

    success := false

    // 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()

    // Use the PKCS11 driver (.dll, .so, .dylib) for your particular HSM.
    // (The format of the path will change with the operating system.  Obviously, "C:/" is not used on non-Windows systems.
    pkcs11.SetSharedLibPath("C:/Program Files (x86)/Gemalto/IDGo 800 PKCS#11/IDPrimePKCS1164.dll")

    // Establish a logged-on session.
    // Use your actual PIN here.
    pin := "0000"
    userType := 1
    success = pkcs11.QuickSession(userType,pin)
    if success == false {
        fmt.Println(pkcs11.LastErrorText())
        pkcs11.DisposePkcs11()
        return
    }

    // Note: A logged-on session is required to list private keys.

    json := chilkat.NewJsonObject()
    json.SetEmitCompact(false)

    success = pkcs11.FindAllKeys("private",json)
    if success == false {
        fmt.Println(pkcs11.LastErrorText())
        pkcs11.DisposePkcs11()
        json.DisposeJsonObject()
        return
    }
