java加密解密算法工具包。其中包括MD5,SHA1,AES,DES,RSA等对称或对称加密算法



# 1.RSA使用方法

## 1.1 生成公私钥

```java
	static String publicKey;
	static String privateKey;

	/**
	 * 生成公私钥
	 */
	@Before
	public void init() {
		try {
			Map<String, Object> keyMap = RSAUtil.genKeyPair();
			publicKey = RSAUtil.getPublicKey(keyMap);
			privateKey = RSAUtil.getPrivateKey(keyMap);
			System.out.println("公钥: \n\r" + publicKey);
			System.out.println("私钥： \n\r" + privateKey);
		} catch (Exception e) {
			e.printStackTrace();
		}
	}

```

## 1.2 RSA对文件进行加解密

```java
		try {
			String dir = RSATest.class.getResource("/").getFile();
			File sourceFile = new File(dir+File.separator+"test.txt");
			System.out.println(sourceFile.getAbsolutePath());
			File targetFile = new File(dir+File.separator+"test_rsa.txt");
			//加密
			RSAUtil.encryptByPrivateKey2File(sourceFile, targetFile, privateKey);
			String sign = RSAUtil.sign(targetFile, privateKey);
			
			//签名检查
			boolean status = RSAUtil.verify(targetFile, publicKey, sign);
			assertTrue(status);
			
			//解密
			File targetFile2 = new File(dir+File.separator+"test_rsa_de.txt");
			RSAUtil.decryptByPublicKey2File(targetFile, targetFile2, publicKey);
			
		} catch (Exception e) {
			e.printStackTrace();
			throw new EncryptException();
		}
```
