ZHI.ZSystem是github上一款開源的幫助函式庫。。其針對.NET System庫內部物件實現了大量的擴充套件方法,同時還集成了超級多的幫助類,以便於我們日常程式設計開發。最重要的是它基於.NET Standard 2.0目標框架編寫,.NET Core 與.NET Framework編碼工程師們都可以使用,不用根據版本下載,是不是超讚!

今天要介紹的幫助類就是用於AES加密解密用的EncryptHelper。接下來我們用一段程式碼來展示它的用法:
//把如下程式碼貼進單元測試方法後,“執行測試”就可檢視加密解密結果啦! //AES KEY 128 BIT var aes_key = "afbbc5713904a815"; //AES IV 16 BYTE var aes_iv = "9420f687309c817c"; // plaintext var plaintext = "我們來進行單元測試咯!.}|/=@#¥%……&*()——+~··"; //BASE64 輸出 var ciphertext_base_64_output = EncryptHelper.AESEncryptToBase64(plaintext, aes_key, aes_iv, AesCipherMode.CBC, AesPaddingMode.PKCS7Padding);//Hex 輸出(十六進位制輸出) var ciphertext_hex_output = EncryptHelper.AESEncryptToHex(plaintext, aes_key, aes_iv, AesCipherMode.CBC, AesPaddingMode.PKCS7Padding); //AES 解密 BASE64 var base_64_decrypt = EncryptHelper.AESDecryptFromBase64(ciphertext_base_64_output, aes_key, aes_iv, AesCipherMode.CBC, AesPaddingMode.PKCS7Padding);//AES 解密 Hex var hex_decrypt = EncryptHelper.AESDecryptFromHex(ciphertext_hex_output, aes_key, aes_iv, AesCipherMode.CBC, AesPaddingMode.PKCS7Padding); Console.WriteLine("CBC密碼模式"); Console.WriteLine(" 加密結果base64輸出:{0}", ciphertext_base_64_output); Console.WriteLine(" 加密結果hex輸出:{0}", ciphertext_hex_output); Console.WriteLine(" 解密base64:{0}", base_64_decrypt); Console.WriteLine(" 解密hex:{0}", hex_decrypt); Console.WriteLine(); //BASE64 輸出 ciphertext_base_64_output = EncryptHelper.AESEncryptToBase64(plaintext, aes_key, aes_iv, AesCipherMode.CFB, AesPaddingMode.PKCS7Padding); //Hex 輸出(十六進位制輸出) ciphertext_hex_output = EncryptHelper.AESEncryptToHex(plaintext, aes_key, aes_iv, AesCipherMode.CFB, AesPaddingMode.PKCS7Padding); //AES 解密 BASE64 base_64_decrypt = EncryptHelper.AESDecryptFromBase64(ciphertext_base_64_output, aes_key, aes_iv, AesCipherMode.CFB, AesPaddingMode.PKCS7Padding); //AES 解密 Hex hex_decrypt = EncryptHelper.AESDecryptFromHex(ciphertext_hex_output, aes_key, aes_iv, AesCipherMode.CFB, AesPaddingMode.PKCS7Padding); Console.WriteLine("CFB密碼模式"); Console.WriteLine(" 加密結果base64輸出:{0}", ciphertext_base_64_output); Console.WriteLine(" 加密結果hex輸出:{0}", ciphertext_hex_output); Console.WriteLine(" 解密base64:{0}", base_64_decrypt); Console.WriteLine(" 解密hex:{0}", hex_decrypt); Console.WriteLine();
貼出單元測試的輸出結果:

剛才的案例程式碼中,向大家展示了AES的CFB密碼模式加密。相比例項化.NET內建的AES加密物件,這種靜態方法呼叫的方式,是不是方便許多啦!
