Examples with Key java.security.Key used on opensource projects

Example 6 with Key

use of java.security.Key in project hbase by apache.

the class TestEncryptionUtil method testKeyWrapping.

// There does not seem to be a ready way to test either getKeyFromBytesOrMasterKey
// or createEncryptionContext, and the existing code under MobUtils appeared to be
// untested.  Not ideal!
@Test
public void testKeyWrapping() throws Exception {
    // set up the key provider for testing to resolve a key for our test subject
    // we don't need HBaseConfiguration for this
    Configuration conf = new Configuration();
    conf.set(HConstants.CRYPTO_KEYPROVIDER_CONF_KEY, KeyProviderForTesting.class.getName());
    // generate a test key
    byte[] keyBytes = new byte[AES.KEY_LENGTH];
    new SecureRandom().nextBytes(keyBytes);
    String algorithm = conf.get(HConstants.CRYPTO_KEY_ALGORITHM_CONF_KEY, HConstants.CIPHER_AES);
    Key key = new SecretKeySpec(keyBytes, algorithm);
    // wrap the test key
    byte[] wrappedKeyBytes = EncryptionUtil.wrapKey(conf, "hbase", key);
    assertNotNull(wrappedKeyBytes);
    // unwrap
    Key unwrappedKey = EncryptionUtil.unwrapKey(conf, "hbase", wrappedKeyBytes);
    assertNotNull(unwrappedKey);
    // only secretkeyspec supported for now
    assertTrue(unwrappedKey instanceof SecretKeySpec);
    // did we get back what we wrapped?
    assertTrue("Unwrapped key bytes do not match original", Bytes.equals(keyBytes, unwrappedKey.getEncoded()));
    // unwrap with an incorrect key
    try {
        EncryptionUtil.unwrapKey(conf, "other", wrappedKeyBytes);
        fail("Unwrap with incorrect key did not throw KeyException");
    } catch (KeyException e) {
    // expected
    }
}

Example 7 with Key

use of java.security.Key in project hbase by apache.

the class TestEncryptionUtil method testWALKeyWrappingWithIncorrectKey.

@Test(expected = KeyException.class)

    // set up the key provider for testing to resolve a key for our test subject
    // we don't need HBaseConfiguration for this
    Configuration conf = new Configuration();
    conf.set(HConstants.CRYPTO_KEYPROVIDER_CONF_KEY, KeyProviderForTesting.class.getName());
    // generate a test key
    byte[] keyBytes = new byte[AES.KEY_LENGTH];
    new SecureRandom().nextBytes(keyBytes);
    String algorithm = conf.get(HConstants.CRYPTO_WAL_ALGORITHM_CONF_KEY, HConstants.CIPHER_AES);
    Key key = new SecretKeySpec(keyBytes, algorithm);
    // wrap the test key
    byte[] wrappedKeyBytes = EncryptionUtil.wrapKey(conf, "hbase", key);
    assertNotNull(wrappedKeyBytes);
    // unwrap with an incorrect key
    EncryptionUtil.unwrapWALKey(conf, "other", wrappedKeyBytes);

Example 8 with Key

use of java.security.Key in project hbase by apache.

Example 9 with Key

use of java.security.Key in project hbase by apache.

the class HFileReaderImpl method createHFileContext.

Example 10 with Key

use of java.security.Key in project hbase by apache.

the class EncryptionUtil method unwrapKey.

/**

   * configured master and alternative keys, rather than having to specify a key type to unwrap
   * with.
   *
   * The configuration must be set up correctly for key alias resolution.
   *
   * @param conf the current configuration
   * @param keyBytes the key encrypted by master (or alternative) to unwrap

   * @throws IOException if the key cannot be unwrapped
