Jasypt With Properties File

How to?

Jasypt的EncryptableProperties類別，提供讀取加密過後的properties檔案，其中密文以ENC()包住。

password=ENC(xWWu6PWYHwfVmNMTXCJG5A\=\=)
account=root

以下為測試範例，存檔是透過一般的Properties類別，需要加密的部分透過PropertyValueEncryptionUtils類別去做轉換；讀檔則使用EncryptableProperties類別:

	@Test
	public void test() throws IOException{
		 StandardPBEStringEncryptor encryptor = new StandardPBEStringEncryptor();
		 encryptor.setPassword("jasypt");
 
		Properties p = new Properties();
		p.setProperty("account", "root");
		p.setProperty("password", PropertyValueEncryptionUtils.encrypt("123456", encryptor));
 
		File file = new File("test.properties");
		file.createNewFile();
 
		FileOutputStream fos = null;
		try {
			fos = new FileOutputStream(file);
			p.store(fos, "gg");
		} finally {
			close(fos);
		}
 
		EncryptableProperties ep = new EncryptableProperties(encryptor);
 
		FileInputStream fis = null;
		try {
			fis = new FileInputStream(file);
			ep.load(fis);
		} finally {
			close(fis);
		}
 
		Assert.assertEquals("root", ep.getProperty("account"));
		Assert.assertEquals("123456", ep.getProperty("password"));
	}
