TEE Encryption V4.2.1 (Windows)

TEE Encryption V4.2.1

Downloads

Platform	File	How to run
Windows	TEE_Encryption_V4.2.1.exe	Double-click — no installation needed
Linux	TEE_Encryption_V4.2.1_Linux.tar.gz	Extract, then chmod +x start_linux.sh && ./start_linux.sh

The Linux package auto-installs everything (system libraries + Python packages) on first run, then launches the GUI. Verified on Ubuntu 26.04 LTS (Python 3.14).

What's new in V4.2.1

• Fixed: Keyfile silent-fallback — if a keyfile is set but unreadable, operation is aborted with a clear error
• Fixed: Window & taskbar icon now shows the golden lock instead of Flet's default
• Fixed: libiconv.dll crash on EXE startup
• New: Linux support with one-command auto-installer (start_linux.sh)
• New: Second Hash button in the input area
• Fixed: Cross-platform clipboard (Windows / macOS / Linux)

Cross-save

Files encrypted on Windows, Linux or Android are fully interchangeable.
Same password + same keyfile = same result on every platform.
(Verified: a file encrypted on Windows decrypts correctly on Linux.)

Encryption

• AES-256-GCM with PBKDF2-HMAC-SHA256 (200,000 iterations)
• Fresh random salt + IV per operation — no nonce reuse
• Optional keyfile as second factor
