In an alternate universe where Tor uses 3DES. Also 3DES effective strength is 112 bit and I can't be bothered to read up on why again.
Edit: oh, now that I look at the specification at the time of writing 3DES was a permitted cipher in Tor. So the captioned statement could be ... accurate?
I guess I foolishly assumed she was doing her own encryption over https or something (I have no idea if that's even possible. I've taken one network security class)
Encrypting your IP address would be like encrypting your mailing address. Like, ok buddy, but you're not going to be able to use that to receive any mail so not sure what your goal is -- you're still going to have to use your plain address if you want to receive anything.
