Contoh Java berikut menggunakan skema perjanjian RawPrivateKeyToStaticPublicKey kunci untuk secara statis mengkonfigurasi kunci pribadi pengirim dan kunci publik penerima. Kedua pasangan kunci berada di ECC_NIST_P256 kurva.

Contoh berikut membuat ECDH keyring Raw dengan skema perjanjian PublicKeyDiscovery kunci. Gantungan kunci ini dapat mendekripsi catatan apa pun di mana kunci publik dari kunci pribadi yang ditentukan cocok dengan kunci publik penerima yang disimpan di bidang deskripsi materi dari catatan terenkripsi.

// Instantiate material providers
var materialProviders = new MaterialProviders(new MaterialProvidersConfig());
	    var AlicePrivateKey = new MemoryStream(new byte[] { });
