find the name of my missing encryption software

I have attached an encrypted file that I generated on a hard drive that has just completely physically died. This encrypted file was stored off site along with others I now need to decrypt. I know the password for this file to be decrypted I just cannot remember which file encryption program I used. I do remember the following about the program, after entering password you used your mouse, for as long as you wanted, and by scrolling it around the program window you generated a larger and larger key (which you could see getting larger in another field in the window ) until you were satisfied.. I seem to recall the icon for the program was a few squares clumped together in (I think colors were ) red, blue, yellow I have spent a full day looking for it and can't find it. I have also found out that generally .sec files are pgp encoded but i see symantec has all that fairly well tied up and it wasn't one of their products, I believe it was shareware or outright freeware. If you take the contract and know the product I will send you the password and you will return the decoded file and the name of the software I forgot so I can get it back again
