示例1: outputSizeTests

import org.bouncycastle.crypto.modes.GCMBlockCipher; //导入方法依赖的package包/类
private void outputSizeTests()
{
    byte[] K = new byte[16];
    byte[] A = null;
    byte[] IV = new byte[16];

    AEADParameters parameters = new AEADParameters(new KeyParameter(K), 16 * 8, IV, A);
    GCMBlockCipher cipher = initCipher(null, true, parameters);

    if (cipher.getUpdateOutputSize(0) != 0)
    {
        fail("incorrect getUpdateOutputSize for initial 0 bytes encryption");
    }

    if (cipher.getOutputSize(0) != 16)
    {
        fail("incorrect getOutputSize for initial 0 bytes encryption");
    }

    cipher.init(false, parameters);

    if (cipher.getUpdateOutputSize(0) != 0)
    {
        fail("incorrect getUpdateOutputSize for initial 0 bytes decryption");
    }

    // NOTE: 0 bytes would be truncated data, but we want it to fail in the doFinal, not here
    if (cipher.getOutputSize(0) != 0)
    {
        fail("fragile getOutputSize for initial 0 bytes decryption");
    }

    if (cipher.getOutputSize(16) != 0)
    {
        fail("incorrect getOutputSize for initial MAC-size bytes decryption");
    }
}
