Add support for Slovenian eID

[craftbyte]

Would it be possible to support (either on APDU or PKCS#11 level) Slovenian eIDs? You can find documentation here and here. The official library is available here. If you need any extra documentation/support, I can also provide a contact at the government department that oversees eIDs.

Yes, we can add Slovenian eID support. We need your help with testing, we'll get back to this as time allows.

Can you perhaps provide at least the initial version yourself? It should be relatively easy to start with PKCS#11 level, see e.g. Czech eID support PR.

Here are step-by-step instructions for adding Slovenian eID support at the PKCS#11 level:

---

1. Modify electronic-id.hpp

• Locate the ElectronicID class and add an entry for Slovenian eID.

  SloEID, // Add this line below the last eID type

---

2. Modify electronic-id.cpp

• Extend the SUPPORTED_ATRS map with the Slovenian eID ATR and its corresponding constructor. Replace <ATR_VALUES> with the Slovenian eID ATR values.

  // SloEID
  {{<ATR_VALUES>},
   constructor<Pkcs11ElectronicIDType::SloEID>},

---

3. Modify Pkcs11ElectronicID.cpp

• Add a helper function to define the PKCS#11 module path for Slovenian eID.

  inline fs::path slovenianPkcs11ModulePath()
  {
  #ifdef _WIN32
      return system32Path() / L"sloveniankp11.dll";
  #elif defined __APPLE__
      return "/path/to/SLOEID/libsloveniankp11.dylib";
  #else // Linux
      return "/path/to/libsloveniankp11.so";
  #endif
  }

• Add the Slovenian eID configuration to the SUPPORTED_PKCS11_MODULES map.

  {Pkcs11ElectronicIDType::SloEID,
   {
       "Slovenian eID (PKCS#11)"s,  // name
       ElectronicID::Type::SloEID,  // type
       slovenianPkcs11ModulePath().make_preferred(), // path
       
       JsonWebSignatureAlgorithm::RS256, // authSignatureAlgorithm
       RSA_SIGNATURE_ALGOS(),            // supportedSigningAlgorithms
       3,     // retryMax
       true,  // allowsUsingLettersAndSpecialCharactersInPin
       false, // providesExternalPinDialog
   }},

---

4. Modify Pkcs11ElectronicID.hpp

• Add SloEID to the Pkcs11ElectronicIDType enum.

  SloEID, // Add this below the last entry
