示例1: testCreateExportKey
import org.keyczar.Encrypter; //导入依赖的package包/类
@Test
public void testCreateExportKey() throws KeyczarException {
// create the key, export the public key; 1024 bits is the smallest size
GenericKeyczar keyczar = Util.createKey(
DefaultKeyType.RSA_PRIV, KeyPurpose.DECRYPT_AND_ENCRYPT, 1024);
KeyczarReader publicKeyReader = Util.exportPublicKeys(keyczar);
Encrypter encrypter = new Encrypter(publicKeyReader);
// test that it works
String ciphertext = encrypter.encrypt(MESSAGE);
Crypter crypter = new Crypter(Util.readerFromKeyczar(keyczar));
String decrypted = crypter.decrypt(ciphertext);
assertEquals(MESSAGE, decrypted);
// test a session
StringBuilder longMessage = new StringBuilder("hello message ");
while (longMessage.length() < 500) {
longMessage.append(longMessage);
}
ciphertext = Util.encryptWithSession(encrypter, longMessage.toString());
