(Go) PKCS11 Login / LogoutSee more PKCS11 ExamplesSample code showing how to login and logout of a PKCS11 session. A session becomes authenticated when Login is called, and returns to the unauthenticated state when Logout is called. A smart card's PIN is passed to the Login method. Note: This example requires Chilkat v9.5.0.88 or later.
// 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("aetpkss1.dll") success := pkcs11.Initialize() if success == false { fmt.Println(pkcs11.LastErrorText()) pkcs11.DisposePkcs11() return } // Pass -1 for the slotID to open a session on the first non-empty slot. slotID := -1 // Open a session. readWrite := true success = pkcs11.OpenSession(slotID,readWrite) if success == false { fmt.Println(pkcs11.LastErrorText()) pkcs11.DisposePkcs11() return } // Make it an authenticated session by calling Login. // The smart card PIN is passed to the Login method. // The user type can be one of three choices: // 0 - Security Officer // 1 - Normal User // 2 - Context Specific. // You'll likely always login as the Normal User. userType := 1 pin := "0000" success = pkcs11.Login(userType,pin) if success == false { fmt.Println(pkcs11.LastErrorText()) success = pkcs11.CloseSession() pkcs11.DisposePkcs11() return } // Do what is needed with the authenticated session... // ... // ... // Revert to an unauthenticated session by calling Logout. success = pkcs11.Logout() if success == false { fmt.Println(pkcs11.LastErrorText()) success = pkcs11.CloseSession() pkcs11.DisposePkcs11() return } // When finished, close the session. // It is important to close the session (memory leaks will occur if the session is not properly closed). success = pkcs11.CloseSession() if success == false { fmt.Println(pkcs11.LastErrorText()) pkcs11.DisposePkcs11() return } fmt.Println("PKCS11 Login and Logout successfully demonstrated.") pkcs11.DisposePkcs11() |
