1. VB 如何利用磁碟的序列號進行軟體加密
讀序列號可以做到，關於怎麼生成注冊碼，演算法就要自己搞定了你可以轉成16進制，再運算生成10進制再用ASCII碼轉出字元……方法很多讀序列號可以用別人寫的DLL，也可以用代碼 http://hi..com/superitman/blog/item/fb356eec1026d8d52e2e2165.html關於演算法，就不多說了，因為是你自己的程序，自己寫個演算法別人一般不容易知道如果你的程序不是很出名，也不用怕被人破解，別人沒空破解簡單的小程序如果你真怕被破解，幾乎沒有辦法防破解，因為再怎麼難的演算法都沒有最後都是用一個判斷語句來判斷是否是已經注冊的，會匯編的只要把True改成False，錯的注冊碼也能注冊最好是用資料庫加密，也就是你做的程序如果是有資料庫的，你不需要為程序加密只要把程序用到的資料庫用注冊碼加密，這樣別人就必須要用注冊碼，因為中間沒有判斷語句錯的注冊碼就不能為資料庫解密，就讀不出數據了 看我打字打得這么累，就麻煩認真看下，謝謝！
2. 利用硬碟獲得注冊碼怎麼破解怎麼破解利用硬碟序列號計算的軟體注冊碼
一般是反匯編軟體，看它的加密方式。。。
這個直接給用戶碼和注冊碼，就相當於給你一個密碼，然後要求你破解。。。一般很困難~~~
3. 如何用硬碟序列號加密共享軟體
同一廠家的U盤的序列號是唯一的，但是現在的U盤山寨產品比較多，U盤的序列號可以在量產時根據設定的組合生成可以出現重復，另外U盤的序列號不是一成不變的，可以用量產工具改變
U盤的固件里沒有完全固定不變的參數
4. 怎樣利用硬碟號給軟體加密.(EXE文件加密)
可以試試採用外殼加密方式，不過你要用加密狗，隨便請一家公司比如彩虹狗等他們都提供外殼加密方式，注我不是廠家推銷商！^_^。

6. 關於硬碟序列號加密
用硬碟序列號加密的軟體大多是一些專業軟體，這種軟體安裝時檢測你的硬碟序列號，然後封裝到軟體文件中，一般情況沒有辦法逆向解密！建議你用當初安裝的源盤重新安裝！
