二、加密测试
MD5加密测试
/** * MD5加密 */public class MD5Test { public static void main(String[] args) {String string = "你好 世界";String byteArrayToHexString = MD5Utils.byteArrayToHexString(string.getBytes());System.out.println(byteArrayToHexString);//e68891e698afe4b880e58fa5e8af9d }}
base64加密测试
/** * base64加密 */public class Bast64Tester { public static void main(String[] args) {String string = "你好 世界";String encodeData = Base64Util.encodeData(string); //加密String decodeData = Base64Util.decodeData(encodeData); //解密System.out.println(encodeData);//5oiR5piv5LiA5Liq5a2X56ym5LiySystem.out.println(decodeData);//你好 世界 }}
SHA加密测试
/** * SHA加密 */public class ShaTest { public static void main(String[] args) {String string = "你好 世界"; String sha256Crypt = Sha2Crypt.sha256Crypt(string.getBytes());System.out.println(sha256Crypt);//$5$AFoQTeyt$TiqmobvcQXjXaAQMYosAAO4KI8LfigZMGHzq.Dlp4NC }}
