Hello, I seek the most powerful encryption tool available that works on Windows XP. Can anyone recommend one? At least 384 bit is crucial because I absolutely need to be as secure as possible with these files. I got caught once and if it happens again I'm screwed. I will be encrypting movie files, mostly .AVI files if that helps. I would use this encryption so that the encrypted files could not be identified during transfer over the internet, and only the person who downloads the file could ever be able to determine the file is a even a movie, whether that be via password protection or anything. The files will be transferred through an FTP site. My plan is to compress the original file, let's say a .AVI file, to a password protected zip file, then rename both the file and extension to some random numbers and letters like "a4s5.7k4" then encrypt the file and rename it again to some other random letters and numbers. I am hoping this will prevent the files people download from me from being identified during transfer by a third party. I know, you say "Well how do you know the person downloading from you is legit?" or "How will the person downloading it be able to restore it to the original .AVI file?" I have resolved this issues so they are no longer a problem so all that's left is this encryption scheme. Any recommended progs, advice, tips, any info at all would be greatly appreciated. Thanks.
