Example 11 with KeyChain

use of com.facebook.crypto.keychain.KeyChain in project conceal by facebook.

the class SimpleDecryptTest method setUp.

protected void setUp() throws Exception {
    super.setUp();
    SoLoader.init(this.getInstrumentation().getContext(), false);
    KeyChain keyChain = new FakeKeyChain();
    mCrypto = AndroidConceal.get().createCrypto128Bits(keyChain);
    mIV = keyChain.getNewIV();
    mKey = keyChain.getCipherKey();
    // Encrypt some data before each test.
    mData = new byte[CryptoTestUtils.NUM_DATA_BYTES];
    ByteArrayOutputStream cipherOutputStream = new ByteArrayOutputStream();
    OutputStream outputStream = mCrypto.getCipherOutputStream(cipherOutputStream, new Entity(CryptoTestUtils.ENTITY_NAME));
    outputStream.write(mData);
    outputStream.close();
    mCipheredData = cipherOutputStream.toByteArray();
}
