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);
}
}
