Hello everybody, my name is Sigflup. Sigflups in a slobble. That is welcome to another
|
|
episode of Hacker Public Radio in this episode. I'm going to be talking about
|
|
encrypting all your stuff with blowfish, which is fun. This is going to be the
|
|
easy way to do it. I've been doing this for a while and I've been sitting here
|
|
like in my place wondering what to do, kind of bored. I don't feel like doing
|
|
anything productive and so I thought I should do something productive. It's just
|
|
to force myself to do something productive and like well let's make a radio
|
|
show and so I poked around my computer like what could we do and then I noticed
|
|
all these files that ended with that BF. I tend to encrypt these files and I
|
|
always end them with that BF and those are the files that encrypt just that BF
|
|
that blowfish and I could do that. I could talk about that. So this is what I'm
|
|
going to talk about. I'm going to talk about encrypting your stuff with blowfish.
|
|
Blowfish being a cipher and it's going to be real simple. It's going to be
|
|
simple as hell. So this is what you do. If you want to encrypt a file you type
|
|
open SSL. You have it. You probably have open SSL. If your computer can
|
|
generate, if your computer can generate SSH keys, you probably have it. So I'm
|
|
willing to bet you have it. If you just type open SSL, I'm willing to bet that
|
|
you have it. Type open SSL, space BF, space-e and then encrypt stuff. Simple as
|
|
that. You type that in and you enter in a key and it takes the standard input
|
|
and encrypt it to the standard output. So you pipe it in a file and pipe it out
|
|
to another file and there you go. It's simple as that. Now to decrypt you use
|
|
change it to open SSL, space BF, space-d and then you type in your key and
|
|
that decrypts it. So simple as that. Put those in the show notes. I usually
|
|
use it to encrypt movie files because I'm just a bit paranoid about people
|
|
seeing movies on my computer going, oh well, where do you get all these movies?
|
|
So I tend to obfuscate the names and encrypt them. And so it's just a matter of
|
|
decrypting them. You can decrypt them too. You can just decrypt it to standard
|
|
out. So you can decrypt it to an M-player instance, which is nice, which is
|
|
what I like to do. And so, yeah, there you go. Open SSL. You can do a lot more
|
|
step with open SSL, like credit SSL search, for instance. That was my
|
|
person encounter with open SSL. You can do just all sorts of things. There's
|
|
probably a man page for it. So have fun with it. And take care everyone.
|
|
Thanks for listening. Bye-bye.
