如何在C＃中使用AES 128位加密字符串？

问题描述

im使用Oracle Database12c在asp.net中的Web应用程序上工作 我使用aes128存储过程对密码进行加密 这是进行加密的过程

DECLARE
   l_user_id    test.username%TYPE := 'SCOTT';
   l_user_psw   VARCHAR2 (2000) := 'mypassword123';

   l_key        VARCHAR2 (2000) := '1234567890999999';
   l_mod NUMBER
         :=   DBMS_CRYPTO.ENCRYPT_AES128
            + DBMS_CRYPTO.CHAIN_CBC
            + DBMS_CRYPTO.PAD_PKCS5;
   l_enc        RAW (2000);
BEGIN
   l_user_psw :=
      DBMS_CRYPTO.encrypt (UTL_I18N.string_to_raw (l_user_psw,'AR8MSWIN1256'),l_mod,UTL_I18N.string_to_raw (l_key,'AR8MSWIN1256'));
   
      DBMS_OUTPUT.put_line ('Encrypted=' || l_user_psw);

   INSERT INTO test VALUES (l_user_id,l_user_psw);
dbms_output.put_line('done');
   COMMIT;
END;
/

最终结果是

现在我想在C＃中制作相同的Aes 我知道我可以从C＃调用存储过程并获得相同的结果 但出于安全原因，我想使用C＃制作 我尝试了很多方法，但结果却不同！ 我需要帮助！

解决方法

由于我很慷慨，我将为您提供解决方案：

public static string EncryptPassword(string key,string password)
{
    // Your current code uses WIN1256 encoding for converting
    // your strings to bytes,so we'll use that here
    var encoding = System.Text.Encoding.GetEncoding(1256);
    byte[] passwordBytes = encoding.GetBytes(password);
    byte[] keyBytes = encoding.GetBytes(key);

    using (var aes = AesManaged.Create())
    {
        // Set up the algorithm
        aes.Padding = PaddingMode.PKCS7;
        aes.Mode = CipherMode.CBC;
        aes.Key = keyBytes;
        aes.BlockSize = 128; // AES-128
        // You don't specify an IV in your procedure,so we
        // need to zero it
        aes.IV = new byte[16];

        // Create a memorystream to store the result
        using (var ms = new MemoryStream())
        {
            // create an encryptor transform,and wrap the memorystream in a cryptostream
            using (var transform = aes.CreateEncryptor())
            using (var cs = new CryptoStream(ms,transform,CryptoStreamMode.Write))
            {
                // write the password bytes
                cs.Write(passwordBytes,passwordBytes.Length);
            }
            
            // get the encrypted bytes and format it as a hex string and then return it
            return BitConverter.ToString(ms.ToArray()).Replace("-",string.Empty);
        }
    }
}
