此Demo包含兩個文件，建立一個解決方案，然後建立兩個文件，一個為Form，一個為Class，把代碼分別複製進去即可

RSA正確的執行過程：
加密解密：
1、獲取密鑰，這裡是產生密鑰，實際應用中可以從各種存儲介質上讀取密鑰
2、加密
3、解密
簽名和驗證：
簽名：
1、獲取密鑰，這裡是產生密鑰，實際應用中可以從各種存儲介質上讀取密鑰
2、獲取待簽名的Hash碼
3、簽名
其中，1和2的步驟無所謂，在本例中，我們將對txtSource裡的內容進行簽名，也可以對文件進行簽名
驗證簽名：
1、獲取密鑰，這裡是產生密鑰，實際應用中可以從各種存儲介質上讀取密鑰
2、獲取待驗證簽名的Hash碼
3、獲取簽名的字串，這裡簽名的字串存儲在m_strEncryptedSignatureData變量中，在DEMO中必須通過簽名才能獲得這個字串，因此需要先執行簽名，當然也可以更改之後通過別的方式獲得
4、驗證
其中，1和2的步驟無所謂，在本例中，我們將對txtSource裡的內容進行簽名驗證，也可以對文件進行簽名驗證
如果是文件，取得文件之後把文件的內容以byte[]的方式代入即可
