示例1: decrypt

import java.security.interfaces.RSAPublicKey; //導入方法依賴的package包/類
public static String decrypt(PublicKey publicKey, String cipherText)
		throws Exception {
	Cipher cipher = Cipher.getInstance("RSA");
	try {
		cipher.init(Cipher.DECRYPT_MODE, publicKey);
	} catch (InvalidKeyException e) {
           // 因為 IBM JDK 不支持私鑰加密, 公鑰解密, 所以要反轉公私鑰
           // 也就是說對於解密, 可以通過公鑰的參數偽造一個私鑰對象欺騙 IBM JDK
           RSAPublicKey rsaPublicKey = (RSAPublicKey) publicKey;
           RSAPrivateKeySpec spec = new RSAPrivateKeySpec(rsaPublicKey.getModulus(), rsaPublicKey.getPublicExponent());
           Key fakePrivateKey = KeyFactory.getInstance("RSA").generatePrivate(spec);
           cipher = Cipher.getInstance("RSA"); //It is a stateful object. so we need to get new one.
           cipher.init(Cipher.DECRYPT_MODE, fakePrivateKey);
