CrypKey SDK 和 CrypKey Instant 的比較。一些 CrypKey SDK 提供的高級功能包括：

• 創(chuàng)建自定義對話框
• 保護程序的特定方面（例如打印功能）而不保護整個程序
• 確定程序的用戶體驗中需要何種程度的授權(quán)
• 包含在Crypkey SDK 和 CrypKey Instant 中的 CrypKey 自有的 CloneBuster 技術能夠防止通過訪問和記錄永久、只讀的硬盤序列號（HDSN）來進行硬盤拷貝

CrypKey SDK’s 其他創(chuàng)新特性包括：

• 企業(yè)網(wǎng)絡許可 —— 使受保護程序在企業(yè)網(wǎng)絡任何地方可以工作
• 增強許可轉(zhuǎn)移 —— 允許用戶從許可池中移出或移入許可
• eTransfer —— 允許許可快速容易地從一臺計算機通過 internet 轉(zhuǎn)移到另一臺
• 分離 NGN 處理 —— 允許用戶在使用 CrypKey 時調(diào)試程
序

• CrypKey USBKey 支持 —— 允許給客戶提供一個硬件密鑰而不是電子密鑰，不需要改動源碼
• 被證實的技術特性 —— 提供給你所有 CrypKey’s 強大技術，包括可選的特性，例如 CloneBuster，用來防止硬盤克?。籆rypKey Stealth，用來防止逆向工程

Compare CrypKey SDK and CrypKey Instant. Some examples of the advanced functionality offered in CrypKey SDK include the ability to:

• create custom dialog boxes
• protect specific aspects of an application (e.g., print functionality) without protecting the application in its entirety
• determine at what point during the user’s experience with the application that authorization is required
• CrypKey’s own CloneBuster technology, which prevents hard drive copying through accessing and logging permanent, read-only hard drive serial numbers (HDSN), is common to both Crypkey SDK and CrypKey Instant.

CrypKey SDK’s other innovative features include:

• enterprise network licensing — enables a protected program to function anywhere on the enterprise network
• enhanced license transfer — permits users to transfer licenses out of and back into a license pool
• eTransfer — allows licenses to be quickly and easily transferred from one computer to another via the internet
• separate NGN process — permits users to debug a program while using CrypKey
• CrypKey USBKey support — allows you to give your customers a hardware key, versus an electronic key, without requiring code changes
• proven technology features — gives you all of CrypKey’s robust technologies, including optional features such as CloneBuster, to prevent hard drive cloning; and CrypKey Stealth, to prevent reverse engineering
