• 操作步驟簡單。

• 支持拖放。

• 不需要Adobe Acrobat軟件。

• 批量設(shè)置歸檔中所有PDF的權(quán)限。

加密PDF

• 設(shè)置開放或用戶密碼保護PDF未經(jīng)授權(quán)的開放。

• 設(shè)置所有者密碼以保護PDF免受未經(jīng)授權(quán)的編輯、打印和應(yīng)對。

保護PDF不被授權(quán)使用

• 防止未經(jīng)授權(quán)的用戶打印PDF。

• 防止復(fù)制PDF的文本或圖形。

• 防止更改或編輯PDF內(nèi)容。

Encrypt PDF Command Line

Encrypt PDF Command Line提供常規(guī)控制臺接口,除了Encrypt PDF (GUI)所有功能以外，還具備以下功能：

• 提供命令行應(yīng)用程序。

• 支持通配符作為例子中的星號：* .pdf。

• 在CGI（服務(wù)器端）中簡單易使用。

兩種類型的PDF密碼

• 所有者/主密碼

• 用戶/打開密碼

注意：其源PDF必須是未加密的PDF。如果該PDF是加密的，則Acrobat Reader將在底部狀態(tài)欄里顯示一把鑰匙。

可以使用所有者密碼來保護PDF文件不被打印、編輯、更改和復(fù)制。使用所有者密碼，用戶可以獲得對PDF文件的完全訪問權(quán)。這意味著如果打印被禁用，則需要使用所有者密碼來打印PDF文件。第二種類型是用戶密碼。如果你想讀一個開放的受密碼保護的PDF文件，就需要用戶密碼。

Note：The source PDF must be an unencrypted PDF. Acrobat Reader will show a key in the bottom status bar if the PDF is encrypted.

There two passwords you can apply to a PDF. The first is the owner password. Opening a PDF with this password will allow you full access to the PDF when a user password has been assigned as well. This means that even if printing was disabled you will still be able to print the PDF when using this password. No password will be prompted for when opening the PDF if you secure it with only an owner password. The second is the user password. Opening a PDF with this password will restrict you based on how the PDF was password protected (printing may be disabled, for instance).
