Create a window program that lunch into the system tray.
Once it lunched, it will add the EDCryption option to the “Right Mouse click” Menu of any textbox or rich-text editor that allowed cut and paste.
The “Right Mouse Click” option should show up in any textbox object in the browser, Microsoft Word, Note, Email client, Skype, Yahoo Messenger, Meeting, Google Talk, or anywhere textbox object is use in window applications.
Here is how the UI should operate:
After the EDCrption program activated, right mouse click bring up a menu with an added option “EDCryption”; mouse over the EDCryption, it pop out Encrypt and Decrypt option as sub-menu.
Encryption: When user click on Encrypt, it will take the text content in the clipboard or the high-lighted text in the textbox, run it through the encryption method and replace the original high-lighted text with the encrypted text if the textbox allowed edit or add the encrypted text in clipboard if the textbox doesn’t allow edit.
Description: When any encrypted text were high-lighted; or the clipboard contains encrypted text, it will delete the encrypted text and replace it with the decrypt text if the textbox allow edit or pop up a window and display the decrypted text for read only textbox.
The encryption and decryption algorithm will be provided in a DLL ( i will send this to the successful bidder); the programmer will only have to handle the user interface
