Encryping stuff

Thanks for the episode. You seem to do more interesting things in your normal computer use than the rest of us do. I'm interested in hearing more like this in the future. What seems mundane to you is really interesing to us regular desktop users.

Is there a reason to use blowfish in partucular? When you say "enter your key", do you mean enter the password for the key created earlier? I've created keys with and without password before. If you want to see an encrypted file using a text editor or movie player, is there a program or script you use as a front end to decypt and play on the fly, or do you decrypt and then handle the file separately? I'm wondering if you use a GTK or Python popup to ask for the key password or something like that.

yo

Blowfish because it's fun. No other reason.

Key as in the same key you entered. You are not creating a key/password pair, you are manually entering a key in and you're entering it in twice. once for decrypting and once for encrypting.

I would handle decrypting separately. If you script/write something that handle's encrypted files that would be nice. So far I've just been piping them into things.

I hope that answers your questions. Mail me if it doesn't. pantsbutt @ @ g mail . com

THANKS FOR LISTENING!!!!!!
