In this tutorial, we’ll take a look on how to encrypt and decrypt a file using existing JDK APIs. 2. Writing a Test First We’ll start by writing our test, TDD style. Since we’re going to work with files here, an integration test seems to be appropriate. As we’re just using ...
public static String encryptBASE64(byte[] key) throws Exception{ return (new BASE64Encoder()).encode(key); } } 2.MD5(Message Digest Algorithm)加密 MD5 是将任意长度的数据字符串转化成短小的固定长度的值的单向操作,任意两个字符串不应有相同的散列值。因此 MD5 经常用于校验字符串或者文件,因为如果文...
