CT File Encrypt

Introduction

CT File Encrypt can encrypt your private documents using strong AES-256 encryption without password.

Encryption and decryption are easy. Just drop the file into it, that it! No password required. It is designed for encrypting small size (< 10MB) documents, photo, screenshots, etc. before uploading to cloud storage or restrict others to access.

Important: The private key will be generated automatically in %USERPROFILE%\key for the first time. The key is unique, SAVE it to a secure and safe place. You can zip it with password (7z with AES-256 protected recommended) for the backup. DON'T lost it otherwise you won't be able to open your encrypted files anymore.

Note: Folders are not supported yet. But you can drag multiple files into it.

簡介

CT File Encrypt 可以把你重要的文件、相片用 AES-256 加密。一拖即加密/解密、無須密碼！ 用，其間有畀過其他人試用，開始時已計劃開源，只是沒有時間整埋源碼，今次終於放上了 GitHub 了。

重要訊息： 第一次開啟時，會在 %USERPROFILE% 中建立 key 這個檔案。這個 key 是唯一的，萬一不見了，我也沒有辦法幫你解密檔案，請小心保管！可以用 7z AES-256 把它備份好。

依賴庫

• OpenSSL 1.1.1
• Qt 5.9

支援平台

Windows 及 Mac OS X

已知問題

• 未支援資料夾 (可先 zip or tar)，但支援拖多個檔案
• 未對大檔案 (> 10MB) 優化，因原為文件、相片設計
• 使用 MinGW 編譯會失去對非 ASCII 檔案名的支持
