WinGPG developed by Scand Ltd. is a tray-based classical Windows application and a classic GPGv2 distribution (we use the cryptography from the official site without making any modifications).
It supports the following operations:
Encryption/Decryption (we offer automatic zipping at encryption time, so your files are ready to be transmitted via email or any instant messenger immediately)
Key management (create, import, export, revoke)
WinGPG main operational features are:
WinNT Explorer support via context menus;
Global shortcuts working from the active explorer window or clipboard;
Clipboard support for both texts and files;
No complicated setup, you only run a batch file;
WinGPG is a fully functional tool, which offers the user an opportunity to manage keys and files easily. Password protected keys, default keys, and other useful tricks are available with WinGPG.
