Windows 檔案加密用哪套?AxCrypt 能做什麼

AxCrypt 軟體圖示 AxCrypt 2.1.1547 資料更新 2017-12-06 閱讀約 6 分鐘

你手上有一批檔案不想讓別人看到——可能是合約掃描檔、客戶個資、論文初稿,或是存了各種帳號密碼的記事本。你想把它們鎖起來,但想到要學一套新軟體就覺得麻煩,又怕哪天自己忘了密碼,檔案永遠打不開。你需要的不是把整顆硬碟都鎖起來的龐大方案,而是「想鎖哪個檔案就鎖哪個」的輕量工具。

一般人最直覺的做法是壓成加密壓縮檔,但每次要改內容就得解壓縮、編輯、再壓回去,來回幾次就煩了。另一種做法是整顆硬碟加密,但那只對整台電腦有效,單獨寄一個檔案給別人時還是沒保護。這類工具的切入點是:直接對單一檔案加密,右鍵按下去就完成,要開啟時雙擊輸入密碼即可,不改變你原本的工作流程。

AxCrypt 操作介面
AxCrypt 的操作介面

01AxCrypt 到底是做什麼用的?

它是一套 Windows 上的單檔加密工具,用 AES 128-bit 或 256-bit 加密個別檔案。安裝後會整合進檔案總管的右鍵選單,對檔案按右鍵選「AxCrypt」就能加密,雙擊加密檔輸入密碼就能開啟編輯。也支援指定資料夾為「安全資料夾」,新放進去的檔案會自動加密。官方說明強調不需要額外設定,裝完就能用。

02右鍵加密具體是怎麼操作的?

安裝過程可以選擇是否整合進檔案總管。之後對想加密的檔案按右鍵,選「AxCrypt」,可以設定哪些人能存取、要不要設到期日,再輸入你的密碼就完成。要解密時雙擊該檔案、輸入密碼即可。加密後的檔案可以正常寄給別人,對方如果沒有這套軟體,你用密碼分享給對方,對方也能解開。

03加密之後的檔案能不能寄給沒裝這套軟體的人?

可以。官方 FAQ 明確說,收件人不需要安裝 AxCrypt,你用 passphrase 分享給對方,對方用你提供的密碼就能解密。這表示加密檔可以透過 Email 或任何方式傳送,對方拿到檔案和密碼就能開啟。不過對方要能編輯檔案,還是需要安裝軟體,這點要自己確認。

04它跟雲端硬碟能不能搭配使用?

可以。官方說明提到它會自動偵測電腦上安裝的雲端儲存服務,建立一個 AxCrypt 資料夾,放進去的檔案會自動加密。官方列出的支援服務包含 Dropbox、Google Drive、Microsoft OneDrive。做法是先把檔案加密再上傳到雲端,這樣雲端上的檔案就是加密狀態,即使雲端帳號被盜,檔案內容也無法讀取。

05密碼管理功能是怎麼回事?

它現在有密碼管理功能,可以線上安全儲存所有密碼和代碼,包含信用卡資訊、安全筆記,支援產生強密碼、離線存取和匯出資料。這個功能是另外計費的,每月 1 美元或每年 0.83 美元,不限裝置數。如果你本來就在找密碼管理器,這套軟體等於一次涵蓋檔案加密和密碼管理兩種需求。

06個人使用者適合用這套嗎?

適合。它的設計就是給個人用的——右鍵加密、雙擊解密、不需要設定,這些都是為了讓非技術背景的人也能上手。付費方案 Premium 每月 5 美元,包含安全資料夾、金鑰分享、雲端整合、行動裝置加密、密碼管理等功能。免費的 VIEWER 版只能解密別人分享給你的檔案,或你自己之前加密的檔案,不能加密新檔案。

07企業管理者用這套有什麼好處?

它有一個 MasterKey 功能,讓企業管理員可以取回成員加密的檔案。員工離職或忘記密碼時,管理員可以用 MasterKey 解開檔案,避免公司檔案永久遺失。另外近期推出了群組管理功能,可以建立使用者群組、指派群組角色、用群組 MasterKey 管理檔案存取。Business 方案每人每月 12 美元,包含企業管理員 MasterKey 和企業優先支援。

08免費版夠用嗎?

免費版只能解密既有檔案,不能加密新檔案,所以如果你要拿來加密自己的檔案,免費版等於不能用。付費的 Premium 方案才有完整的加密功能。另外要注意,它沒有密碼恢復機制——官方明確說如果你忘記 passphrase,沒有任何方式可以救回加密檔案。這點在決定使用前要想清楚。

09介面只有英文,會不會很難上手?

官方資料顯示介面是英文,但官方說明提到軟體本身支援 13 種語言,包含英文、荷蘭文、法文、德文、義大利文、韓文、葡萄牙文、西班牙文、瑞典文、土耳其文、俄文、波蘭文等,沒有列出繁體中文。如果你對英文介面不習慣,操作上可能要多花一點時間摸索,但右鍵選單的加密選項位置固定,實際需要閱讀的英文不多。

10這套軟體還有在更新嗎?

收錄的版本紀錄顯示,從 2016 年到現在共收錄 37 個版本,最近一次更新在 2026 年 6 月,但近 12 個月只更新 1 次,近 24 個月也只有 1 次。更新頻率不算高,但至少還有在維護。如果你在意軟體是否持續獲得安全更新,這點需要自己衡量。

11忘了密碼的話,檔案是不是就永遠打不開了?

是。官方 FAQ 直接說明,它沒有辦法存取你的 passphrase,如果你忘記了,加密檔案就無法恢復。這是這類加密軟體的共通特性——為了確保只有你能解密,開發商自己也不留後門。建議的做法是設定密碼時就寫在安全的地方,或使用密碼管理功能來記住。

12跟 Folder Lock 或 TrueCrypt 比起來,這套有什麼不同?

資料中有列出幾套功能相近的軟體,包含 Folder Lock(287 人評分)、Remote Desktop Manager Enterprise(121 人評分)、CrococryptFile(99 人評分)、USB Secure(58 人評分)、TrueCrypt(57 人評分)。AxCrypt 的評分是 7.6/10,共 99 人評分。它的特色是單檔加密和右鍵整合,而 TrueCrypt 是整顆硬碟或磁區加密,Folder Lock 則偏向檔案保險箱和資料夾鎖定。如果你要的是「個別檔案加密、寄給別人也能開」,AxCrypt 的定位比較接近;如果你要的是整顆硬碟加密,應該看 TrueCrypt 那類工具。
