Document

Returns an estimate of the number of bytes that can be read (or skipped over) from this input stream without blocking, which may be 0, or 0 when end of stream is detected.

Usage

From source file:com.cedarsoft.crypt.CertTest.java

@Test
public void testKey() throws Exception {
    InputStream inStream = new DataInputStream(getClass().getResource("/test.der").openStream());
    byte[] keyBytes = new byte[inStream.available()];
    inStream.read(keyBytes);//  w w  w .  j  av a 2 s.  c om
    inStream.close();

    KeyFactory keyFactory = KeyFactory.getInstance("RSA");

    // decipher private key
    PKCS8EncodedKeySpec privSpec = new PKCS8EncodedKeySpec(keyBytes);
    RSAPrivateKey privKey = (RSAPrivateKey) keyFactory.generatePrivate(privSpec);
    assertNotNull(privKey);

    Cipher cipher = Cipher.getInstance("RSA");
    cipher.init(Cipher.ENCRYPT_MODE, privKey);

    byte[] bytes = cipher.doFinal(PLAINTEXT.getBytes());
    assertEquals(SCRAMBLED, new String(Base64.encodeBase64(bytes)));
