优雅的java加解密工具类-支持RSA，AES，MD5，Base64，Hex，ROT

一.RSA TestCase

public class TestRSAAlgorithm {

public static void main(String[] args) {
    testFull();
}

public static void testFull() {
    //TODO Hex test
    RSAAlgorithm rsaAlgorithm = RSAAlgorithm.create().codec(CodecEnum.Base64).build();
    try {
        Map<String, Object> map = rsaAlgorithm.init();
        System.out.println(map.size());
        String privateKey = rsaAlgorithm.getPrivateKeyStr(map);
        System.out.println("privateKey:"+privateKey);
        System.out.println("privateKey_length:"+privateKey.length());

        String publicKey = rsaAlgorithm.getPublicKeyStr(map);
        System.out.println("publicKey:"+publicKey);
        System.out.println("publicKey_length:"+publicKey.length());

        String str = "orclight2018";

        System.out.println("encrypt by public key & decrypt by private key");
        String encryptByPublic_ret = rsaAlgorithm.encryptByPublic(str,publicKey);
        System.out.println("result:"+encryptByPublic_ret);
        System.out.println("result:"+encryptByPublic_ret.length());

        String decryptByPrivate_ret = rsaAlgorithm.decryptByPrivate(encryptByPublic_ret,privateKey);
        System.out.println("result:"+decryptByPrivate_ret);
        System.out.println("result:"+decryptByPrivate_ret.length());

        System.out.println("-----------------------------------------");

        System.out.println("encrypt by private key & decrypt by public key");
        String encryptByPrivateKey_ret = rsaAlgorithm.encryptByPrivate(str,privateKey);
        System.out.println("result:"+encryptByPrivateKey_ret);
        System.out.println("result:"+encryptByPrivateKey_ret.length());

        String decryptByPrivate = rsaAlgorithm.decryptByPublic(encryptByPrivateKey_ret,publicKey);
        System.out.println("result:"+decryptByPrivate);
        System.out.println("result:"+decryptByPrivate.length());

    } catch (NoSuchAlgorithmException e) {
        e.printStackTrace();
    }
}

}

二.AES Testcase

public class TestAESAlgorithm {

public static void main(String[] args) throws Exception {

    AESAlgorithm aesAlgorithm = AESAlgorithm.create().keySize(AesKeySizeEnum.size128)
            .cipherAlgorithm(AesCipherAlgorithmEnum.CBC_PKCS5PADDING)
            .codec(CodecEnum.HEX).build();

    String key = "1234567890qweasd";
    String siv = "qweasd1234567890";

// String key = "1234567890qweasd12345678"; String data = "next action is tomorrow Am 8";

    System.out.println("加密前的字串是：" + data);
    String signature = aesAlgorithm.encrypt(data, key, siv);
    long start = System.currentTimeMillis();

    long end = System.currentTimeMillis();
    System.out.println("加密后的字串是：" + signature);
    System.out.println("加密 cost:" + (end - start));
    System.out.println("4e7f89c7f2a791c59010fb31ee977b77acaba5ad503201c4ff320857a1b04904".equals(signature));

    start = System.currentTimeMillis();
    String DeString = aesAlgorithm.decrypt(signature, key, siv);

    System.out.println("解密后的字串是：" + DeString);
    end = System.currentTimeMillis();
    System.out.println("解密 cost:" + (end - start));
}

}

三.base64 Testcase

public class Base64AlgorithmTest {

public static void main(String[] args) throws Exception {
    String content = "next action is tomorrow AM:8";
    String encode = Base64Algorithm.encode(content);
    String decode = Base64Algorithm.decode2String(encode);
    System.out.println("原文："+content);
    System.out.println("加密后："+encode);
    System.out.println("解密后：" + decode);
}

}
